Love JetBlue!!!

Best service of any airline so far. But your chairs are super uncomfortable.

Sep 13, 2019

Bulkhead seat, so had leg room which was great. Unfortunately, seats uncomfortable. Short in the thigh support.

Sep 12, 2019

Had my seat changed by delta and the one I was given was last in premium economy and across from bathroom. And not with my family . I just had hip surgery and needed the extra room. Disappointed. Across from bathroom was horrible.

Although everyone onboard the plane were fantastic, the woman at the counter as we got off the plane was rude. I went up to her to tell her my seat belt was broken, and she acted like I was bothering her, and didn’t care what I had to say
