Having the most legroom in coach* makes traveling with a lap infant or nursing child—or just getting that car seat in place—less of a wrestling match. (And speaking of wrestling, at least one lavatory on every JetBlue plane is equipped with a diaper-changing table, so you don't have to attempt it at your seat.)
Want to spread out even more?
When you purchase an Even More® Space seat you get up to 7” more legroom (all the better to build a fort or inflight racetrack), early boarding and Even More® Speed, a fast-track to the TSA checkpoint (in select airports). Some Even More Space seats are located toward the front of the plane, which allows for faster and easier boarding and deplaning.
