The flight was rescheduled and canceled. I had to go with another airline last minute to honor my school commitment. The reimbursement is a joke -$150 for a one way plane ticket.

The flight was rescheduled and canceled. I had to go with another airline last minute to honor my school commitment. The reimbursement is a joke -$150 for a one way plane ticket.

The flight itself was A+ but boarding sucked. They boarded all passengers at once, and as a result I did not get to put my carryon in an overhead bin near me so I had to wait till near the end to deplane.

Really appreciate the great crew and pilot for keeping us informed about everything going on, updates, etc. It's so reassuring just to know (for example) why there might be a delay, etc. I'm very satisfied with the excellent service.

This was my first time flying Breeze. The plane was one of the nicer planes I have been on. The flight attendants were friendly and helpful. I will fly them again.

Well, Kayak should have communicated with Breeze that when I purchased the ticket, Kayak should have relayed that I had one carry on as part of my ticket purchase. So, KAYAK, tell the airlines!

Why do I need to spend $$$ to sit together as a family? It’s beyond frustrating, we were all sitting apart.

Easy boarding and great communication, smooth flight- all was great!

This was the first time that I traveled on Breeze Airways and I was very surprised at how well everything went. The flights attendants were very friendly and always had a smile in their face. I will not hesitate to travel on them again.

Overall positive. If I am headed to the one destination they fly to from my home airport, I will fly again without question. I think because the airport provided the check in and boarding I didn’t fully know what to expect. The A220 is a comfortable ride with big windows and feels open. I’m glad I didn’t bid to upgrade to the first class product. It is just a better seat with little extra amenity. But was very happy with the extra leg room seats and bundle we booked.

Flights were consistently delayed and we were given no reason for the delays. We could not check our bags until two hours before the flight boarded in Myrtle Beach, even though we were there and there was someone manning the check-in at the terminal. It is also asinine to charge $70 to check your luggage at the terminal, but charge $35 if you choose to check your luggage via the Breeze app. The seats were comfortable enough and the flights were quick once we actually got on the plane and off the tarmac. But again, we were constantly delayed.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

New boarding doesn't make sense. Filling front first is slow.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

Our flight was delayed several times. It left 9 hours after scheduling. We had to sleep in the airport.

The gate area was terrible at San Diego airport -way too crowded in a small space. Since my husband was driving to our destination, we did not have to take any luggage so my kids and I only had backpacks. Therefore everything was easy and smooth. And we didn’t have to pay up charges for everything and it was a short flight. I tried table was broken and it was a little cramped, but it was fine for what we needed. I probably would not fly spirit on a longer flight and if I had to take baggage.

Boarding procedure is horribly slow. You charge me to check a bag and would not let me carry it on. Charged me to simply select a seat. Charged me for water. Charged me for every little thing on top of paying for an expensive ticket. Your seats are terrible. So uncomfortable, they don’t recline. No WiFi, no way to charge my phone. No entertainment. I mean you Offer noting and you charge for everything. Why would anyone want to fly with you again?

The staff from LAX to New Orleans were rude but the staff from New Orleans to LAX were nice!

Paid extra for a “comfy seat” which was anything but!

It was cancelled unexpectedly so we rented a car and drove home.

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).

Flight was delayed 8 hours so far. Don’t expect to fly when choosing Spirit Airlines. I will happily pay more to never deal with this company again.

This airline is effective for the price you pay, do not expect anything extra at all. You have to pay extra for seat assignment , carry on luggage, food, you name it ...and even if you pay extra for better seats they do not recline.

Got on quickly and easily. When it turned out the other two seats in my row would be occupied, a nearby flight attendant immediately let me know that I could move one row behind me since it was an empty row, I moved into the window seat where I could relax enough to take a little nap. Can’t ask for much more.

Awful. My flight was three hours late leaving DFW and we just arrived at LAX three hours late and stuck on the runway. I heard the Spirit workers at the desk in DFW say that we were waiting on a crew. I am extremely disappointed in Spirit.

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.

Most horrible airlines. Please avoid it. It's ok to spend $50 extra for delta, united or Alaska

The trip was good but the last minute changes I didn’t like because I had already talked to the attendee and they didn’t help me with my ticket I was having trouble checking in and when the time was up they help me but charge me for that and last minute luggage it was a small bag. After I was in the airplane I realized you were charging because the flight was almost empty and you have to get the money some how. Thanks for everything.

Our flight was delayed by four hours without notice, the app for getting my boarding pass is super confusing, and I wasn’t able to check a suitcase without paying for a higher cost package
