On 9/25/22 I booked a ticket for $183; I cancelled this trip in February. I applied the $183 flight credit + $1.30 (credit card) to book a new trip on 5/25/23. It's looking like I'll need to cancel that trip as well. If I cancel that trip, a) what kind of credit will I receive, and b) what will the expiration date be?

My main question is whether the expiration/travel by date of the original $183 flight credit will be reset by having applied it to a new ticket.
