AA is claiming to me that 24 hour cancellation rule doesn't apply if using trip credit to book a basic economy ticket and they are refusing to let me cancel a basic economy ticket I just booked with trip credit Is this true? Doesn't seem right to me - they can't point to anything in terms and conditions saying this. My reading of trip credit is if cancelling within 24 hours, the refund goes back to original form of payment (in this case the trip credit). Help?
