Read the new fare names
JetBlue’s current booking help distinguishes Main Base from Main and Main Flex. Main Base permits paid reservations before the final 24 hours, with automatic assignment later when available. Main and Main Flex include selection during booking or through Manage Trips.
Do not mix the A321 versions
JetBlue’s fleet pages distinguish all-Core A321 layouts from Mint-equipped and Long Range versions. Select the marketed version shown for your flight. EvenMore is a named product within the Main seating inventory; Mint is a separate premium product, not a reason to label all front seats identically.
Use the airline’s seat view for exact positions
Our JetBlue configuration references still need complete numbered diagrams before publication. Check the live booking map for the actual row letters and product assignment, and consult JetBlue’s separate exit-row requirements if you are considering an emergency-exit position.
