3. OVERVIEW Air Canada s principal objective is to become one of the world s top global airlines. In pursuing this goal, it focuses on continuous improvement in customer experience and employee engagement and creating value for shareholders by targeting four core priorities: Identifying and implementing cost reduction and revenue enhancing initiatives; Pursuing profitable international growth opportunities and leveraging competitive attributes to expand margins, in large part by increasing connecting traffic through its strategic international gateways in Toronto, Vancouver and Montreal, and growing and competing effectively in both the business and leisure market to and from Canada; Engaging customers by continuously enhancing their travel experience and providing a consistently high level of customer service, with additional emphasis on premium and business passengers and products; and Fostering positive culture change through employee engagement programs. This includes meaningful investments in training and other tools that support delivering exceptional customer experience and that also promote improved collaboration and an appreciation of how the airline and its talented employees can better work together in a supportive and enriching environment. Additional information on Air Canada s strategy can be found in section 4 Strategy of Air Canada s 2017 MD&A. Financial Summary The following is an overview of Air Canada s results of operations and financial position for the second quarter of 2018 compared to the second quarter of 2017. Record operating revenues of $4,333 million in the second quarter of 2018, an increase of $423 million or 11% from the second quarter of 2017. On capacity growth of 7.5%, record passenger revenues of $3,921 million increased $371 million or 10.4% from the second quarter of 2017. Operating expenses of $4,107 million in the second quarter of 2018, an increase of $489 million or 14% from the second quarter of 2017. CASM increased 5.6% from the second quarter of 2017. Adjusted CASM decreased 1.0% from the second quarter of 2017, better than the 0.5% to 1.5% increase projected in Air Canada s news release dated April 30, 2018. Air Canada s better than projected adjusted CASM performance was largely driven by the acceleration of aircraft lease extensions (mainly from the third quarter of 2018) which resulted in a decrease to maintenance provisions, the impact of cost reduction initiatives related to Air Canada s cost transformation program, and other operating expense reductions. Adjusted CASM is a non-gaap financial measure. Refer to section 14 Non-GAAP Financial Measures of this MD&A for additional information. Operating income of $226 million in the second quarter of 2018 compared to operating income of $292 million in the second quarter of 2017. EBITDAR of $646 million in the second quarter of 2018 compared to EBITDAR of $681 million in the second quarter of 2017. The airline reported a second quarter 2018 EBITDAR margin of 14.9% compared to an EBITDAR margin of 17.4% in the second quarter of 2017. Special items are excluded from all of Air Canada s reported EBITDAR calculations. Refer to section 4 of this MD&A for information on special items. EBITDAR is a non-gaap financial measure. Refer to section 14 Non-GAAP Financial Measures of this MD&A for additional information. 5

A net loss of $77 million or $0.28 per diluted share in the second quarter of 2018 versus net income of $311 million or $1.13 per diluted share in the second quarter of 2017. In the second quarter of 2018, the net loss included a loss on disposal of assets of $186 million related to the expected sale of 25 Embraer 190 aircraft and losses on foreign exchange of $25 million. In the second quarter of 2017, net income included gains on foreign exchange of $68 million and a gain of $26 million on the sale and leaseback of two Boeing 787 aircraft. Refer to section 4 Results of Operations of this MD&A for additional information. Adjusted net income of $114 million or $0.41 per diluted share in the second quarter of 2018 versus adjusted net income of $226 million or $0.82 per diluted share in the second quarter of 2017. Refer to section 14 Non-GAAP Financial Measures of this MD&A for additional information. At June 30, 2018, adjusted net debt of $6,111 million, a decrease of $5 million from December 31, 2017. An increase in long-term debt and finance lease balances of $889 million was largely offset by an increase in cash and short-term investment balances of $866 million and a decrease in capitalized operating lease balances of $28 million. Adjusted net debt is an additional GAAP measure. Refer to section 6.2 Adjusted Net Debt of this MD&A for additional information. Air Canada s leverage ratio (adjusted net debt to trailing 12-month EBITDAR) was 2.1 at June 30, 2018, unchanged from December 31, 2017. Leverage ratio is a non-gaap financial measure. Refer to section 6.2 Adjusted Net Debt of this MD&A for additional information. Net cash flows from operating activities of $853 million in the second quarter of 2018, an improvement of $24 million from the second quarter of 2017. Negative free cash flow of $13 million represented a decrease of $318 million from the second quarter of 2017 mainly due to Air Canada having received proceeds of $371 million from the sale and leaseback of aircraft in the second quarter of 2017. No such sale and leasebacks were effected in the second quarter of 2018. Return on invested capital ( ROIC ) for the 12 months ended June 30, 2018 of 13.7% compared to ROIC of 15.3% for the 12 months ended December 31, 2017. This decrease was mainly driven by lower adjusted net income and an increase in long-term debt as a result of Air Canada s fleet renewal strategy. ROIC is a non-gaap financial measure.

System Passenger Revenues With the adoption of IFRS 15 Revenue from Contracts with Customers effective January 1, 2018, certain passenger and cargo related fees were reclassified from Other revenue to Passenger revenue and Cargo revenue on Air Canada s consolidated statement of operations, with restatement of 2017 amounts. This reclassification has no impact on total operating revenue. Concurrent with this change in presentation, Air Canada has revised the methodology used to calculate yield and PRASM. These measures are now based on total passenger revenues, with restatement of 2017 amounts on the same basis. In the second quarter of 2018, system passenger revenues of $3,921 million increased $371 million or 10.4% from the second quarter of 2017 on traffic growth of 8.2% and a yield improvement of 2.0%. On a stage-length adjusted basis, yield increased 3.4% when compared to the same quarter in 2017. Business cabin revenues, on a system-basis, increased $98 million or 13.7% from the second quarter of 2017 on traffic and yield growth of 10.3% and 3.1%, respectively. The table below provides passenger revenue by geographic region for the second quarter of 2018 and the second quarter of 2017.

Components of the year-over-year change in second quarter system passenger revenues included: The 8.2% traffic increase which reflected traffic growth in all markets and included gains in the business and premium economy cabins. Consistent with the airline s objective of increasing global international-to-international connecting traffic through its major Canadian hubs (sixth freedom traffic), the traffic growth in the second quarter of 2018 reflected an increase in connecting traffic via Canada to international destinations. The 2.0% system yield increase which reflected: o o o o greater proportional growth of high-yielding business and premium economy passengers; growth in high-yielding local traffic, an improvement in the overall fare mix and increases in fares and carrier surcharges; an increase in ancillary revenues, including through advance seat selection/preferred seating fees and airport paid upgrades; and the introduction of an expanded suite of fare offerings on domestic and U.S. transborder services. These factors were partly offset by the following: o o an increase in average stage length of 2.4%, due to long-haul international expansion, which had the effect of reducing system yield by 1.4 percentage points; and an unfavourable currency impact of $25 million when compared to the second quarter of 2017. 9

In the first six months of 2018, system passenger revenues of $7,410 million increased $740 million or 11.1% from the first six months of 2017.

These factors were partly offset by the following: o o an increase in average stage length of 3.1%, due to long-haul international expansion, which had the effect of reducing system yield by 1.8 percentage points; and an unfavourable currency impact of $48 million when compared to the first six months of 2017. Domestic Passenger Revenues In the second quarter of 2018, domestic passenger revenues of $1,210 million increased $75 million or 6.6% from the second quarter of 2017. The table below provides year-over-year percentage changes in domestic passenger revenues and operating statistics for the second quarter of 2018 and each of the previous four quarters. Canada Year-over-Year by Quarter (% Change) Q2 17 (1) Q3 17 (1) Q4 17 (1) Q1 18 Q2 18 Passenger revenues 4.0 3.0 5.4 5.9 6.6 Capacity (ASMs) 2.8 1.5 1.4 3.4 3.2 Traffic (RPMs) 3.3 1.0 1.6 3.0 2.6 Passenger load factor (pp change) 0.5 (0.4) 0.2 (0.3) (0.5) Yield 0.8 2.2 3.5 2.8 3.9 PRASM 1.4 1.7 3.8 2.5 3.2 (1) To provide a more meaningful comparison, the year-over-year percentage comparisons from 2017 quarters to 2016 quarters are based on previously reported 2016 and 2017 amounts as 2016 amounts have not been restated for the adoption of IFRS 15. Components of the year-over-year change in second quarter domestic passenger revenues included: The 2.6% traffic increase which reflected strong passenger demand on services within Canada as well as incremental connecting traffic to international destinations. The 3.9% yield increase which reflected yield improvements on all major domestic services, including gains in the business cabin as well as the launch of new fare categories on domestic services. In the first six months of 2018, domestic passenger revenues of $2,251 million increased $133 million or 6.3% from the first six months of 2017 on a yield improvement of 3.4% and traffic growth of 2.8%. 11

U.S. Transborder Passenger Revenues Second Quarter 2018 Management s Discussion and Analysis of In the second quarter of 2018, U.S. transborder passenger revenues of $865 million increased $71 million or 8.9% from the second quarter of 2017. The table below provides year-over-year percentage changes in U.S. transborder passenger revenues and operating statistics for the second quarter of 2018 and each of the previous four quarters.

Components of the year-over-year change in second quarter U.S. transborder passenger revenues included: The 6.6% traffic increase which reflected traffic growth on all major U.S. transborder services and included gains in the business cabin. Strong passenger demand between Canada and the U.S. and growth of international-to-international connecting passenger flows from the U.S. were also contributing factors to the yield growth year-over-year. The 2.2% yield increase which reflected yield growth on all major U.S. transborder services with the exception of U.S. short-haul routes. The launch of new fare categories on U.S. transborder services contributed to the yield improvement year-over-year. An unfavourable currency impact of $12 million when compared to the second quarter of 2017 was a partly offsetting factor to the yield growth year-over-year. In the first six months of 2018, U.S. transborder passenger revenues of $1,712 million increased $125 million or 7.9% from the first six months of 2017 on traffic and yield growth of 6.7% and 1.2%, respectively. 12

Atlantic Passenger Revenues In the second quarter of 2018, Atlantic passenger revenues of $1,035 million increased $157 million or 17.8% from the second quarter of 2017. The table below provides year-over-year percentage changes in Atlantic passenger revenues and operating statistics for the second quarter of 2018 and each of the previous four quarters.

Components of the year-over-year change in second quarter Atlantic passenger revenues included: The 15.5% traffic increase which reflected traffic growth on most major Atlantic services and included gains in all cabins. The capacity growth was largely due to the launch of new services from Vancouver to France and Switzerland; from Toronto to Ireland, Portugal, Romania and Croatia; and from Montreal to Ireland, Romania and Portugal. The 1.9% yield increase which reflected yield improvements on all major Atlantic services and included an increase in carrier surcharges year-over-year. An increase in average stage length of 2.2% had the effect of reducing Atlantic yield by 1.3 percentage points. In the first six months of 2018, Atlantic passenger revenues of $1,721 million increased $289 million or 20.1% from the first six months of 2017 on traffic and yield growth of 16.3% and 3.3%, respectively. 13

Pacific Passenger Revenues In the second quarter of 2018, Pacific passenger revenues of $582 million increased $52 million or 9.9% from the second quarter of 2017.

Components of the year-over-year change in second quarter Pacific passenger revenues included: The 5.7% traffic increase which reflected traffic growth on all major Pacific services with the exception of services to Japan and Hong Kong where capacity was reduced year-over-year. The overall traffic increase included gains in the business and premium economy cabins. The 4.0% yield increase which reflected yield growth on all Pacific services. The yield improvement year-over-year was in large part due to an increase in carrier surcharges, particularly in Japan and Korea, and an improvement in the Pacific fare mix. In the first six months of 2018, Pacific passenger revenues of $1,093 million increased $116 million or 11.9% from the first six months of 2017 on traffic and yield growth of 10.4% and 1.4%, respectively. 14

Other Passenger Revenues In the second quarter of 2018, Other passenger revenues (from routes to and from the Caribbean, Mexico and Central and South America) of $229 million increased $16 million or 7.6% from the second quarter of 2017. The table below provides year-over-year percentage changes in Other passenger revenues and operating statistics for the second quarter of 2018 and each of the previous four quarters.

Components of the year-over-year change in second quarter Other passenger revenues included: The 8.6% traffic increase which reflected traffic growth on services to South America and on routes to traditional sun destinations. The traffic growth included gains in all cabins. The 0.9% yield decrease which mainly reflected a yield decline on services to South America and Mexico. Caribbean markets performed well in the second quarter of 2018, with yield growth when compared to the second quarter of 2017. In the first six months of 2018, Other passenger revenues of $633 million increased $77 million or 13.8% from the first six months of 2017 on traffic and yield growth of 12.9% and 0.9%, respectively. Cargo Revenues Cargo revenues of $200 million in the second quarter of 2018 and $368 million in the first six months of 2018 increased $32 million or 19.4% and $52 million and 16.6%, respectively, from the same periods in 2017. When compared to the 2017 periods, cargo traffic and yield increased 10.6% and 8.0%, respectively, in the second quarter of 2018, and 8.7% and 7.3%, respectively, in the first six months of 2018. The growth in traffic was in part due to the introduction of new international routes. In the second quarter and the first six months of 2018, the Atlantic and Pacific markets experienced particularly strong performances from both a traffic and yield perspective. 15

Operating Expenses In the second quarter of 2018, operating expenses of $4,107 million increased $489 million or 14% from the second quarter of 2017 on capacity growth of 7.5%. In the second quarter of 2018, the favourable impact of a stronger Canadian dollar on foreign currency denominated operating expenses (mainly U.S. dollars), compared to the second quarter of 2017, decreased operating expenses by $47 million (comprised of $11 million relating to aircraft fuel expense and an aggregate of $36 million relating to non-fuel operating expenses). In the first six months of 2018, operating expenses of $8,192 million increased $902 million or 12% from the first six months of 2017 on capacity growth of 8.0%. In the first six months of 2018, the favourable impact of a stronger Canadian dollar on foreign currency denominated operating expenses (mainly U.S. dollars), compared to the first six months of 2017, decreased operating expenses by $123 million (comprised of $48 million relating to aircraft fuel expense and an aggregate of $75 million relating to non-fuel operating expenses). The more notable components of the year-over-year change in operating expenses are described below. Aircraft Fuel Expense In the second quarter of 2018, aircraft fuel expense (including fuel expense related to regional airline operations) amounted to $1,099 million, an increase of $302 million or 38% from the second quarter of 2017. This increase reflected higher jet fuel prices (before the impact of foreign exchange), which accounted for an increase of $272 million, and a higher volume of fuel litres consumed, which accounted for an increase of $43 million. These increases were partly offset by a favourable currency impact of $11 million and other factors of $2 million. In the first six months of 2018, aircraft fuel expense (including fuel expense related to regional airline operations) amounted to $2,038 million, an increase of $487 million or 31% from the first six months of 2017. This increase reflected higher jet fuel prices (before the impact of foreign exchange), which accounted for an increase of $443 million, and a higher volume of fuel litres consumed, which accounted for an increase of $98 million. These increases were partly offset by a favourable currency impact of $48 million and other factors of $6 million. Regional Airlines Expense Regional airlines expense of $742 million in the second quarter of 2018 and $1,417 million in the first six months of 2018 increased $94 million or 15% and $137 million or 11%, respectively, from the same periods in 2017. These increases primarily reflected an increase in aircraft fuel expense year-over-year, higher CPA rates versus the same periods of 2017, and increased flying, particularly in the first quarter of 2018. A favourable currency impact was a partly offsetting factor. The growth in CPA rates in the second quarter of 2018 was primarily driven by an increase in engine maintenance expense when compared to the second quarter of 2017, in large part due to a higher volume of maintenance activity. 17

The following table provides a breakdown of regional airlines expense for the periods indicated: (Canadian dollars in millions) Second Quarter 2018 2017 First Six Months Change Change 2018 2017 $ % $ % Capacity purchase fees $ 360 $ 314 $ 46 15 $ 679 $ 622 $ 57 9 Aircraft fuel 135 96 39 41 249 191 58 30 Airport and navigation 76 73 3 4 145 142 3 2 Sales and distribution costs 41 40 1 3 75 77 (2) (3) Depreciation, amortization and impairment 9 7 2 29 18 13 5 38 Aircraft rent 10 10 - - 20 20 - - Other operating expenses 111 108 3 3 231 215 16 7 Total regional airlines expense $ 742 $ 648 $ 94 15 $ 1,417 $ 1,280 $ 137 11 Wages, Salaries and Benefits Expense Wages and salaries expense of $533 million in the second quarter of 2018 and $1,048 million in the first six months of 2018 increased $28 million or 6% and $71 million or 7%, respectively, from the same periods in 2017. These increases were largely due to a higher number of full-time equivalent ( FTE ) employees, largely in support of the airline s international growth. A reduction in stock-based compensation expense, particularly in the second quarter of 2018, was a partly offsetting factor. Employee benefits expense of $178 million in the second quarter of 2018 and $363 million in the first six months of 2018 increased $20 million or 13% and $33 million or 10%, respectively, from the same periods in 2017. These increases were mainly due to the higher level of FTE employees and the impact of lower discount rates, which increased the current service cost of defined benefit pension plans. Airport and Navigation Fees Airport and navigation fees of $237 million in the second quarter of 2018 and $458 million in the first six months of 2018 increased $7 million or 3% and $18 million or 4%, respectively, from the same periods in 2017. These increases were largely due to growth in wide-body and international flying. The favourable impact of Air Canada s agreement with the Greater Toronto Airports Authority, which is allowing the airline to increase international connecting traffic at Toronto Pearson International Airport on a more cost-effective basis, a 3.9% Nav Canada rate reduction effective September 1, 2017, and a favourable currency impact were largely offsetting factors. Aircraft Maintenance Expense In the second quarter of 2018, aircraft maintenance expense of $220 million decreased $6 million or 3% from the second quarter of 2017 reflecting, in large part, the impact of having a greater number of aircraft leases being extended in the second quarter of 2018 and a favourable currency impact. Lease term extensions postpone the expected timing of the end of lease costs and lengthen the period over which expenses are recorded, resulting in a cumulative adjustment to reflect the revised provision required as at the balance sheet date, thus reducing maintenance expense in the period. These increases were partly offset by a higher level of engine maintenance activity year-over-year. In the first six months of 2018, aircraft maintenance expense of $476 million increased $22 million or 5% from the first six months of 2017. This increase was mainly due to a higher level of engine maintenance activity in the first six months of 2018 versus the first six months of 2017, and largely offset by the impact of having a greater number of aircraft leases being extended in the first six months of 2018 versus the same period in 2017, more favourable end-of-lease conditions on aircraft lease extensions, and a favourable currency impact. 18

The following table provides a breakdown of the more significant items included in maintenance expense for the periods indicated: (Canadian dollars in millions) 2018 2017 Second Quarter First Six Months Change Change 2018 2017 $ % $ % Technical maintenance $ 232 $ 220 $ 12 5 $ 457 $ 415 $ 42 10 Maintenance provisions (1) (16) 7 (23) (329) 4 34 (30) (88) Other 4 (1) 5 500 15 5 10 200 Total aircraft maintenance expense $ 220 $ 226 $ (6) (3) $ 476 $ 454 $ 22 5 (1) Maintenance provisions relate to return conditions on aircraft leases which are recorded over the term of the lease. Depreciation, Amortization and Impairment Expense Depreciation, amortization and impairment expense of $278 million in the second quarter of 2018 and $545 million in the first six months of 2018 increased $36 million or 15% and $75 million or 16%, respectively, from the same periods in 2017. These increases were largely due to the addition of Boeing 787 and 737 MAX aircraft into the mainline fleet. Sales and Distribution Costs Sales and distribution costs of $199 million in the second quarter of 2018 and $388 million in the first six months of 2018 increased $11 million or 6% and $19 million or 5%, respectively, from the same periods in 2017. These increases reflected, in large part, the growth in passenger revenue. The favourable impact of new commission programs introduced in North America in April 2018 and growth in direct bookings when compared to the same periods in 2017 were offsetting factors. Ground Package Costs The cost of ground packages at Air Canada Vacations of $114 million in the second quarter of 2018 and $390 million in the first six months of 2018 increased $11 million or 11% and $31 million or 9%, respectively, from the same periods in 2017. These increases reflected higher passenger volumes yearover-year and a higher cost of ground packages (before the impact of foreign exchange), partly offset by a favourable currency impact. Aircraft Rent Aircraft rent expense of $123 million in the second quarter of 2018 and $248 million in the first six months of 2018 decreased $7 million or 5% and $4 million or 2%, respectively, from the same periods in 2017. These decreases reflected a favourable currency impact and the impact of lower rates on certain lease renewals, largely offset by the impact of a greater number of leased aircraft, primarily Boeing 787 aircraft. Special Items In the first quarter of 2017, Air Canada recorded a provision of $30 million relating to a fine which was reinstated by a decision of the European Commission pertaining to cargo investigations. Air Canada paid the fine in the second quarter of 2017. Air Canada has appealed the decision. While Air Canada cannot predict with certainty the outcome of its appeal or any related proceedings, Air Canada believes it has reasonable grounds to challenge the European Commission s ruling. Refer to Current legal proceedings under section 18 Risk Factors of Air Canada s 2017 MD&A for additional information. Other Expenses Other expenses of $344 million in the second quarter of 2018 and $720 million in the first six months of 2018 increased $12 million or 4% and $62 million or 9%, respectively, from the same periods in 2017. These increases reflected, in large part, the capacity growth and Air Canada s international expansion strategy. The first quarter of 2018 included expenses of $26 million related to new uniforms 19
