Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

I like their airplanes because they have plenty of legroom in their seats they always work with me if I have a change of plans on my tickets courteous and I always feel safe flying with them.

In flight on demand didn't work at our seats. Only a single beverage/snack run.

The flights are back on time and everything else runs perfectly.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

In-flight staff was very helpful and excellent. However, the flight was delayed by 90 minutes. Also the boarding process should be expedited in case of delayed flights. This will help the passengers trying to make international connections.

They announced at the last minute that international travelers had to checkin at counter. This created a long line and unnecessary stress.

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Nothing. Jet Blue is a great choice for me And I’m going to miss flying with them Since I travel to Lima Peru very often 😞😞😞
