JetBlue Travel Bank credits are typically valid for 12 months from the date of your original booking[1]. This means that you have one year from the date you initially booked your ticket to use the credits towards a new flight or other eligible JetBlue-related expenses[2]. Please note that this policy may change, so it’s essential to stay updated on JetBlue’s policies and terms.
