Hi everyone, I am traveling next week, and I need to change my flight reservation due to some last minute snafus. I have a round trip ticket, and when I go to the carrier (Delta) to change, I would incur a $200 change fee plus $69 for the fare difference. If I book a one one-ticket (on the return) for the time that I need to change, it is $186. Is there any issue with me doing this? And if not, is there something that I can do to recover any amount from the previous ticket? I could travel with a different airline on the new ticket, and just write off the other ticket. Recommendations? Thank you!
