A fare upgrade refers to changing a non-refundable Wanna Get Away or Wanna Get Away Plus ticket to a refundable fare, such as Anytime or Business Select. You can choose a different fare while changing your flight. The difference between your original Wanna Get Away or Wanna Get Away Plus fare and your new refundable fare is refundable.
For instance, if you originally bought a Wanna Get Away or Wanna Get Away Plus fare for $100 and upgraded it to a refundable Anytime or Business Select fare that costs $300 and later canceled the reservation, you would get a refund of $200. The original $100 will be eligible for use as a flight credit.
