why do other airlines want to take over the ticket? the issuing carrier had received the cash, would the takeover carrier receive the money if they take over a ticket? even during irregular operation like i experienced a few days ago, aa just exchanged the coupon bos lax and use it for payment for bos dfw lax. (i flew 17 segments as a. result.) when qr sees my pnr, it still sees bos lax doh instead of bos dfw lax doh.
