Very quick and easy process from check in to deboarding and baggage claim. Crew was professional and friendly. Flight was smooth and on time. Very convenient for short flights.

I thought that I had pre-purchased carry-on luggage and was surprised when I tried to check in that I did not have it.

You get what you pay for. It’s like a bus but flying. No frills, no snacks. Leg room was fine, boarding was good.

This was my first experience with Breeze. The plane was cleaner and more comfortable than any other I've experienced. The process of boarding was streamlined. We boarded early and arrived at our destination 45 minutes early. The only hiccup was my ticket was rejected by TSA PreCheck and I got sent to the back of a very long line at Fort Myers. I entered my information when I bought my ticket, but it apparently didn't connect to my permanent profile. I'll correct that for next time. I was expecting an Allegiant experience, but Breeze was much more upscale. I really, really enjoyed it.

Ridiculous to have to pay for carry on and to pick seats

Head rest did not move, very uncomfortable. Staff was great. There was no entertainment, would be nice not to have to pay for snack.

This is one of the worst trips that I have ever had. Ending up with an overnight delay. I’m not happy with the fact that they did not provide and set up the arrangement needed for lodging that we had to do it on our own. I also feel there should’ve been Compensation for food.

I like that the price is right! The airplane is clean and the staff is friendly. We landed safely, so that is always a gold star in my book! Great job!

Communication with airline electronically was difficult. No number seemed available to talk to customer service.

The price is amazing. I was worried about how the flight would be as I never flew then. Seats were very comfortable. We had lots of legroom. The Akron airport was really nice. Overall it didn't have the stress we usually experience with flying. Highly recommend

My flight was canceled, and instead of rebooking me on a non-stop first-class flight for the same day, which I originally had, Delta rebooked me on a one-stop flight for the following day. When I checked the Delta app, I noticed that there were available flights for both the same day and the next day. I believe this indicates poor management on their part.

I had only one problem. The temperature on the flight was too COLD. I froze throughout the flight. I thought it might be only my problem but when I went to the restroom during the flight, I saw several people huddling in their jackets. A couple had their winter coats on and I was jealous since I had only a very light jacket.

I am still at the Airport! Delayed Delayed and Delyaed

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

Comfort seating was on the tight side. Maybe it was a smaller plane(?)

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

The pilots were good. Disappointing when planes don't have electrical ports

No complaints - left 20 minutes later than planned but still arrived on time.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

Little warm on the plane and delayed for an hour

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Crew professional. Easy bag drop off. On time. Good entertainment.

They have lost any customer service care and support. Terrible airline now and been for awhile.

The flight was just perfect! We left a few minutes early, had a smooth flight and fortunately had landed before the terrible accident that took off from North Philadelphia airport shortly thereafter.

Multiple gate changes and significant delay leaving DFW. Made for a late arrival

For the price of the ticket you get nothing. The plane had 1 bathroom in the back and when the flight attendant did service no one could use it. No announcement just was told to go back to my seat. Ridiculous and rude.

American Airlines no longer has Bischoff biscuits. This is intolerable.

The flight was delayed. I upgraded to more room. I can't imagine how small the regular seats are I haven't upgraded for my return flight yet.

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.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

Jet Blue has excellent everything, Friendly customer service and staff, clean aircraft’s and is always on time.

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays

Flight cancelled 2 hours prior to boarding. No explanation. No refunds.

I have to congratulate Kayak (and Dylan the Chatdeal agent) because because when we decided extended our trip in Florida by two days, there were many direct flights oprions back to Boston available on the Friday we wanted to fly on the JetBlue website, but once I canceled the original JetBlue flight on their website, those direct return options disappeared immediatley! I think it's a game JetBlue plays. . Luckily, I checked Kayak and they had a direct flight that wasn't appearing on JetBlue's website and so I booked it, and we were able to fly home direct through the Kayak booking when JetBlue was offering nothing (even though I have been a True Blue member for 20 years, and also am a Mosaic member). So much for loyalty- their algorithm for booking is like a shell game. JetBlue used to be a good company but now they're worse than anyone. Also I was originally booked this trip to Florida, two months before the departure date, I booked the trip on JetBlue's website and then after the payment part, they said there was a problem and that I needed to do the booking again, so when I immediately went to rebook , the price had gone up 30%! I called them and it sounded like they had heard this so many times before and the guy told me to check back in 10 minutes and the price would be back to where it was when I was booking- it but it never was. How could the price go up 30% in one minute two months before the flight???? They're playing a game with their customers. Anyways, I booked a cheaper flight then at a less convenient time. So fast forward two months the night before the 7 AM flight, they sent me an email at midnight when I was sleeping to let me know that my flight at 7 AM had been canceled. The only thing they offered was a flight that night from from a different airport (Providence) to a different airport in Florida (West Palm Beach) or a flight two days later. No compensation, nothing. They couldn't of tried to get another plane to the Boston airport? They had all night to do it. I passed on their ridiculous options and flew with Delta and it was a great experience. Of course, I had to pay a lot more booking on the same day, but JetBlue doesn't care. I put in a lengthy complaint with the agent who assured me someone would get back to me by email within three days and I haven't heard a thing. JetBlue used to be a good company but now they're among the worst. The only thing they still have is decent legroom, but the corporate bean counters will probably start taking that away too.
