JetBlue is recoding its retail path around cabin choice, then fare flexibility. Customers will first select Main, EvenMore, BlueFirst or Mint, then move into Base, Standard or Flex pricing within that product, a structure aimed at cleaner comparison and sharper ancillary capture as BlueFirst rolls out later this year. The airline is extending base-fare logic beyond basic economy into Main, EvenMore and BlueFirst, while Mint retains Standard and Flex only. Existing bookings keep their original terms. For JetBlue, the move formalises a more granular offer architecture and positions BlueFirst as a domestic first-class layer on non-Mint aircraft without displacing Mint.
