Pros: The comfort of the plane was great! Lots of room and very comfortable seating.

Cons: I found some members of staff to be a bit rude. When other passengers asked questions or did something wrong (that was a minor issue), one of the staff members in particular talked down to them and treated them like they were stupid.

Pros: Quick boarding. Inexpensive ticket. Direct flight.

Cons: Crew walked thru cabin at least 5 times collecting garbage, but could not hand out sealed snack or sealed water. People sat should-to-shoulder - No buffer space, but asked to leave the plane with 6 foot intervals???? This airline picks and chooses their Covid precautions. Quick and inexpensive flight, if you don’t mind the rest.

Cons: Extremely disappointed about flight 1379 scheduled to depart at 0658, 18 Jun 21. Flight departure was moved to 10:30 AM and later to 12:30 PM without giving any reason for the delay to the hundreds of passengers that arrived at the airport between 4:30 AM to 5:30 AM to meet the airlines requirements. Poor performance by Jet blue. Lost of time and money for me. Thumps down. Blue is my favorite color, live up to it.
