The flight was excellent. The crew was welcoming and attentive.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

The staff at JFK were rude and unhelpful. I was harassed for the same bag that I used on my flight to jfk with no issues claiming it was the inappropriate size. The women then allowed my travel companion to board with the same size bag because they thought she was more “humble”. Also on the flight when informing the flight attendant that nationals no longer have to fill out the Bahamas immigration form my statement was met with eye rolling and attitude.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.
