Basic Reservations Availability Availability Reference: HELP AVAIL Availability can be accessed for flights operating yesterday, today and 352 days in the future. Worldspan creates each availability display at the time of request. All trips display starting closest to the input time for a 24-hour period midnight to midnight. Flights are biased to the carrier requesting the availability. Worldspan displays all flights for the requested airline first, and then other airlines follow in the display.

Availability Basic Reservations Best Trip Within a particular sort level, flights are displayed in best trip order. Airlines use sort level 1. Best trip order is based on the following: Shortest elapsed time. Nonstop flights are considered to have equal elapsed time. Direct flights (same flight number with possible stops and equipment change). Online connections (change in flight numbers on same carrier). Offline connections (change in flight numbers and carrier). Inter-airport connections (changing airport). Class of Service Worldspan displays up to 24 classes of service. The classes are displayed in class order preference determined by the airline. If there are more than 8 classes of service for any one flight, the letters AC followed by 1 appear in the header line. This advises that the first availability screen is displayed. AC2 indicates the second screen is displayed, etc. Flights with additional classes of service contain a dash (-) immediately after the city pair. For connections, the dash is displayed only for applicable flights. If all flights have 8 classes or less, the indicator in the header line does not display. When specific class availability is requested, Worldspan displays the class requested not including screen numbers in the header line or the additional class indicator in the display. Page 2 1002

Availability Basic Reservations Sell connecting flights from availability. ENTRY: 01Y1* OR 01Y1 Y2 Passive Segments References: HELP 0MK HELP 0MAN INFO 0MK INFO 0MAN Passive Segment Notification, or Memo Segments, is a program that transmits notification to the airline advising an existing flight segment has been entered into the Worldspan reservation. This allows the airline to match the reservation in their system with the Worldspan PNR. If the reservation cannot be matched or if the airline is unable to locate a corresponding PNR in their system, a NO action/advice code and an SSR explaining the action is returned. The NO action/advice codes results in the reservation being placed on the subscriber Queue 1 for action. See HELP ACTION for more information on action/advise codes. Passive (MK) space should not be mixed with confirmed (HK) space on the same airline within the same reservation. If the passenger holds a reservation with segments booked through Worldspan and they need to add segments booked directly with an airline, the segments should be entered with an HK action/advice code. The memo segment provides the capability of entering participating carrier space booked directly with the carrier into a reservation. A reservation can be created with memo segments for ticketing. A message is not transmitted to the participating carrier unless they are Passive Segment Notification Participants. Page 8 1002

Availability Basic Reservations Waitlisting References: HELP WL INFO WL A class of service followed by 0 (zero) in an availability display indicates the class of service is not currently available but the passenger can be placed on a waitlist. A waitlist segment should be immediately followed by a confirmed alternate flight for the same city pair or an ARNK segment. Enter multiple waitlists request over the same city pair in order of priority. Airlines can elect to support the use of Priority Waitlist. This allows better control of waitlisted segments. An example use for priority waitlist is waitlist clearance of a passenger on a short flight to make a connection to a long haul flight. Entries For Waitlisting The formats are similar to selling from availability. If the desired class is not available when the sell entry is made, the following response returns. See the following example. 31JUL-TU-9A GCM MIA ** ET KX-DIR END 1 KX 102 Y9 W9 H9 K9 L9 M9 Q9 T9 GCMMIA 735A 955A 73S 0 V0 2 KX 104 Y9 W9 H9 K9 L9 M9 Q9 T9 GCMMIA 1250P 310P 73S 0 V8 3 KX 106 Y9 W9 H9 K9 L9 M9 Q9 T9 GCMMIA 545P 805P 73S 0 V9 ENTRY: 01V1 * KX 102V 31JUL GCMMIA *** 0 AVBL/WL OPEN > Page 10 1002
