The only thing that would make the experience better is a little more leg room and the overhead bins are very low. I hit my head when I was settling into the middle seat and was nervous about poking my eye on the corner of a lowered bin when I was deplaning.

It helps manage expectations to know that this is a discount airline. I brought my own snacks so that I wouldn't have to buy something if I got hungry or thirsty for soda during the flight. One of my seat mates was unaware that he would have to pay $4 for a Coke and was a bit upset. He hadn't listened to the flight attendant say "Drinks for purchase?". All of the employees I interacted with were friendly and professional. My one complaint is that the overhead bins are very low when they are open. I was heading for the middle seat and unexpectedly hit the top of my head on the bottom of the open overhead bin. The headrests were also a little uncomfortable. But overall, for the price, it was a decent value, and I would fly Breeze again.

Flight was on time. The crew was efficient and kind.

Did not like the fact that I was charged to take on a bag I usually put in the overhead

My flight was delayed, not by much.?very good communication during fest and waiting to board.

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

What could have been better is if Discover credit card would be able to purchase food

Crew was inconsistent in instructions in advising passengers about seat backs during take off. Perfunctory announcements except from cabin.

The experience with Breeze was really great. The app makes managing flights easy. You can check in on there 24 hours in advance, and your boarding pass is there, too. The flight crew and the staff at both our airports were wonderful. Snacks and drinks were reasonably priced. The seats were very comfortable, they even had adjustable headrests on every seat. The only downside is not having entertainment or Wi-Fi available onboard.

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

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.

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

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.

There was no wheelchair or wheelchair escort at the gate..unacceptable

No WiFi No TV Bag of chips I guess it could be worse.

From bag drop to boarding, it was great. In-flight is a little different. The seats were a little uncomfortable for that long of a flight. The rest of the cabin crew except for Eva was wonderful. Eva was not friendly at all. I've had to personally encounter her twice in-flight. First time was when I had to go to the lavatory in the back of the plane, and since it was the first for me to board such tiny plane, I didn't know we were using the crew toilet. She was giving me an attitude while telling me where and how to open it since it's not the regular push to open type of door. The second one was when I had to throw trash then use the lavatory again. I asked where to throw them, and unfortunately she was the only crew in the back doodling on her phone, she had to point it out to me with an attitude then told me to wait on the carpet, which I understand because I didn't realize that, but she could have been nicer. After all, I'm a paying customer, and assisting a passenger who isn't knowledgeable about the aircraft is one of the things she's there for. The rest of the experience and crew from bag drop to in-flight were excellent except for her.

It took an hour to get my bag after landing. Not exaggerating

Boarding process on JetBlue is an absolute disgrace. I can’t believe they can’t figure out a better way to board everyone. They called people with disabilities, mosaic and group A all at once and it was a disaster

We flew halfway to our destination (NYC to Burlington) and turned around due to a mechanical issue (landing gear wouldn’t retract automatically). We turned back to JFK for JetBlue’s benefit as we landed safely at JFK and could've just as easily landed safely in Burlington on our Christmas Day flight. Instead the company directed the crew to return the plane to more easily service the aircraft. The passengers landed 3 1/2 hours later and JetBlue gave each passenger $50 for the trouble. Hardly fair compensation to be separated from family on Christmas Day.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries. They dont really bother you about carry-on size, I brought a descent sized backpack and they didnt even check.

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

what I like about Spirit is that the pilot and crew are good communicators. The plane itself - well, its a budget airline and you get what is expected, But I generally just feel safer, somehow, when I know more about what is going on - and Spirit has always done a good job of telling me what is going on: why the delay, why the turbulence, why this and that... and that means a lot to me.

I paid just under 200 for flight and luggage, then paid 200 to change the flight, then paid 100 for a carry on. Then the cancelled the flight. Of the 500 I spent they refunded 250. I bought a delta flight for 270 never flew with spirit, but spirit kept 250, not even refunding the 100 for the carry on though they cancelled the flight (for weather on a day with only a slight rain ).

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

Not have to pay for every single item to take a flight. Seating and delays sucked.

Flight was cancelled and I had to spend the night in the airport lugging my suitcase around

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.
