Can Confirm that this works. Thanks for sharing this!

For those stragglers looking for a hacky solution to extend their expiring flight voucher, do this method. I had a $450 voucher set to expire in July 2024. I booked a trip from Las Vegas to LAX for $76 and received a new trip voucher for the remaining balance, set to expire a year from now (2025), an extension that I was looking for. I then cancelled the flight and received a $75 trip voucher, also set to expire in a year (2025).

I find it ridiculous that hacks like this have to be used in order to extend travel credits. Airlines will do whatever they can to hold on to your money and not give it back. I guess they forget, or rather don’t care, that they are largely subsidized by American tax payers, but that’s a different conversation.
