Booked a basic economy ticket last November (11/2021) using travel back credit expring in May this year (05/2022). I have to cancel the reservation due to confilcts. United says I could pay $45 to upgrade my Basic Economy ticket to Economy ticket, with the economy ticket . United says I could then "Change or cancel your flight without paying a change fee".

Does this mean I could cancel my upgraded basic economy ticket and get my economy fare credit? My travel credit will expire in November this year, irrelavent to my travel bank expiration date (05/2022), correct?
