Reissuing tickets
American Airlines do not allow change fees to be collected as a tax code. To collect any change fee you must reissue the ticket as an even exchange, once the ticket has been exchanged issue a v-MPD with the change fee amount and add the new ticket number to the v-MPD. Please also add the v-MPD number to the PNR via an OSI. See v-MPD for instructions on how to issue.
