OK, help a rookie out here!
Flight next week was booked as an A fare...
AAA-BBB - booked into A
BBB-CCC - single cabin RJ..booked into Y
CCC-BBB - booked into A
BBB-AAA - booked into A
If I attempt an SDC change at T-24 and only want to change the one segment on the single-cabin RJ, is there a way to get the change into A?
