Choice Seats are mostly window and aisle seats toward the front of Coach. Buy Choice Seats on all US Airways and US Airways Express flights during booking or anytime after.
Travel agents issuing an additional charge for an extra seat use the following entry:
In the passenger name box, enter the passenger's last name and first name followed by the notation *EXST* (EG. SMITH/JOHNMREXST).
XX seat messages do not travel from SHARES (US Airways system) unless an action on a segment is taken. Name changes and/or seat assignment cancels will not generate a XX message from US to your OA System.
Any name changes (including adding a middle name or initial) result in the loss of assigned seats.
