Kayak could’ve posted the correct gate number. Almost missed my flight.

Slow boarding, limited food and drink portions. Bad delays and turbulence

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

Truly terrible. Will never willingly fly southwest again. Seats are worse than before they switched to assigned seating. One flight attendant was the opposite of helpful (rude, unhelpful, dismissive, and as my stranger seatmate said unprompted: a total prick). This caused me, 15 minutes into the flight, to book an alternate return flight home on a competing airline (first class 1.2k purchase instead of my existing planned flight) just so I would not have to ever be on that aircraft, with that terrible service person, with those horrific seats ever again.

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

Had a great flight. Delayed takeoff, but comfortable. Snacks were good.

Southwest continues to do less for more money. Flight attendants used to be fun and friendly. But now it’s like they don’t even see you. Such a shame.

I liked it better when you were truer to your roots Am paying more for less fun

I was supposed to be on a later flight. When I showed up at the gate, the woman working there was extremely helpful getting moved up to this earlier flight.

Long layover between flights to Long Island from BWI - need better coordination between flights

They lost my luggage and refuse to help. Terrible airline. I've never experienced worse customer service in my life. Pretty much just told me too bad that I lost all my luggage, not caring that I am stuck in Europe for 2 weeks with absolutely nothing.

You should have had Wifi to make it much enjoyable.

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.

The flight was delayed for more than 3 hours the flight attendant was so angry, it was my first flight with JetBlue but i don’t think I flight with them again.

Since we started at syr the service, crews, and flights were just excellent

Boarding was easy. Provided drinks and snacks. Good aircraft and staff

Not very happy because of the long delaying which causes our luggages were not on the connection flight and nearly missed our connection flight.

It was good. I’m very disappointed that they don’t give commentary ear pods for the movie. I forgot mine at home

Flight was quick, less time than expected, and the attendants all friendly and helpful. We had paid extra for more leg room and were very comfortable. Haven't flown JetBlue in quite a while. Glad to be back!

JetBlue not only has the most comfortable planes, but also used to have the best customer service. Lorie Wright, the lady at the gate was very rude not only to me, but to other passengers as well. Her colleague, the gentleman was also not very friendly. They both were acting like they were doing passengers a favor. The crew on board was very nice.
