JetBlue’s Seat Selection lets you choose specific seats (such as extra legroom or front-of-cabin) for a fee, or for free for Mosaic members.

However for Seat Upgrades involve paying to move to a higher-tier seat, such as EvenMore® (premium economy) or Mint (business class). These are often available via Manage Trips or at check-in, giving you more comfort, amenities, and sometimes early boarding.

Quick Overview

You can select seats during booking, after, or at check-in through the app or website. JetBlue’s plan for “Mini Mint” domestic first-class prototypes is set for June 2026, a move that involves lowering economy legroom (32″ to 30″) to add more premium seating and keep up with industry standards, alongside their ongoing EvenMore enhancements.
