I thought I paid for a round trip for carry-on and my ticket only had one way when I purchased a round trip Didn't make sense to me .Not what you want to hear when it's time to go home.

I thought I paid for a round trip for carry-on and my ticket only had one way when I purchased a round trip Didn't make sense to me .Not what you want to hear when it's time to go home.

Support for wheel chair was not good. Desk did not open until 2 hours before takeoff not check in time.

Boarding process was super smooth and the staff and crew were wonderful. Seats made me feel like I was being bent forward. Might be because I'm shorter and the puffy head rest pushes my head down. I would have liked to have been able to remove it

What entertainment!? Snack i bought was unusual and in very small quantity. Very limited selection of snacks to buy. Taste was mediocre.

Leg room was good. Seat pockets were good. Especially the one for menu. Personal Explanation for potential of needing help since i came on a wheelchair was excellent! That has never happened to me flying before. It happened before many passengers had boarded and the attendant leaned way over in front of me. Great help with my carry on since i was in a wheelchair. I was surprised about cost of drinks and snacks. Didn't know there was no free snack. I was cold on both legs of flight. Asked for a blanket but none was brought. Does Breeze even have them? Temperature was adjusted for a short time. Had to put on jacket and put a shirt from my carry on across my legs. Guy next to me pulled his collar up. My nose was cold to touch. I asked flight attendant if they always kept it that cold. She said she thought they had adjusted the temp. When i suggested she feel how cold my nose was, she said she would note it. Casual dress of crew was interesting to me. I thought tennis shoes was very practical. Observed the captain had gone to get food at a fast food place for the crew before we took off. They did not have time to go having moved from one plane to the next at a different gate than planned. Thought that was great commaradiery! And i told him so. Hard to reach call button and air control. Gate staff suggested we use restrooms before boarding since one on board was so small. Thought that was amusing and thoughtful. Pilot made announcements about delays--mechanical warning light, weather delay, traffic on runway and construction near gate and weather where we were landing. Interesting about crew having to do cleanup. Nice about offering upgrades a couple days before flight. Nice sbout sending reminder to check in.

Flying with this airline is a true nightmare. We got delayed than stranded on layovers due to maintenance issues both ways of our flight and there’s no way to communicate with anyone other than AI bots that are absolutely useless. Never again.

Flight was great except for lunatic lady and her mother sitting middle/window who went nuts when the woman on the aisle wouldn’t stand up right away to let them out even though the aisle was full. Police had to be called. Some people just shouldn’t be allowed to fly.

Flight attendants were wonderful. Seats were comfortable “Nicest” bundle). No screens or meal, but it is a budget airline.

it is an economy airline so lack of perks expected .. however an efficient board, clean plane, pleasant crew and an early arrival for half the price of full service airline

Airplane was newer and very clean, lots of space. Crew was great. There was no food and entertainment but that was expected so not an issue.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

KUDOS TO ALL THE CREW PROVIDING ASSISTANCE WITH PASSENGERS ON A WHEELCHAIR. ON BOTH FLIGHTS THEY HUSTLED TO TAKE MY RELATIVE TO CONNECTION ON TIME. THEY DESERVE A LOT OF CREDIT!

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Very good flight that left on time and arrived earlier than anticipated, which was a plus! The crew members were very welcoming and helpful. However, the temperature on the flight was very cold - almost to the point of extreme discomfort. Additionally, requiring passengers to pay $8 for headphones to access the JetBlue entertainment was disappointing. Those earbud jacks are not used with most technology and would not be able to be used. There was no option to use Bluetooth for my own earbuds. Beyond those inconveniences, the flight was good.

My original flight was cancelled. My replacement flight was delayed over 2 hours. I lost my whole day in NY

Delays were crazy long (over an hour) both for boarding and baggage claim

awful expereince. boarding was a mess and not communicated, then we sat on a hot plane and were at risk of getting kicked off

2 hour delay and a lack of air conditioning on the plane. Not a good combination

Fabulous! This was the first time we've flown with JetBlue and the entire experience was flawless!

First time flying JetBlue and my perception changed. Love it.

Poor, had a 5+ hours delay. Kept sitting in the aircraft with three kids. It was terrible
