This was our first time flying with Breeze Airways, and I can honestly say it won’t be our last! From the pilots and flight attendants to the wonderful staff helping passengers board and exit the plane, everyone was incredibly friendly, kind, caring, and professional. It was clear that everyone took pride in their work and genuinely cared about the passengers’ experience. The airplane itself was exceptionally comfortable, making the entire journey even more enjoyable. What a refreshing experience to fly with an airline that truly puts its passengers first! We look forward to flying with Breeze Airways again and highly recommend them!

Driving 1.5 hours to connect in Charleston to New Haven CT was a waste. New Haven is the worst airport in the US. Everything is outside and this is an issue in bad weather. Zero parking. Only opening 2 hours before wheels up gives you no flexibility. I am done with Breeze. By the time i buy everything i need, im saving no money.

Flight Grand Jct to Las Vegas the internet wasn't working. Flight Las Vegas to Grand Jct we didnt have internet & my air vents was broken making the plane a bit warm. I understand not having a lot of food choices for such a short flight, but not pretzels, cookies or anything offered & only free beverage choices were water, tea, or coffee; not even ginger ale or a soda. Like everything else, you get less & pay more these days.

Breeze Airways is a no nonsense, no extra fluff kind of airline. They have just the basics, boarding is short and easy, and the cost for flights are fair. Will definitely be flying Breeze again!

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.

I was surprised with Breeze Airlines. It was my first time flying with them, and I was hesitant. It was a great experience. The seats are really comfortable. You have much more space than other airlines, and they are better quality seats. The service was amazing, and we landed almost an hour before schedule. It was an amazing experience; I really recommend Breeze Airlines.

Every single flight I take with southwest is delayed by at least one hour. Unbelievable

It’s too cold like fridge and they don’t offer a blanket with expensive price

A List preferred boarding was nice Asked for a mask and cheerfully received Denver bag check-in is tricky. Not near other checking desk. Have to navigate to east security and up to level six for bag checkin. TSA busy and 20 minutes process thru pre lines Denver train to gates quick but one more thing to plan time for and long concourse walk to gate

Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.

Southwest has lost most of what made it special. The flight attendants all used to seem fun and like they were having fun. Now they seem just miserable. They do NOT seem happy to give you your pretzels and drinks. They stick it in your hand or on your tray like it's an annoyance. They bark safety instructions at you. It's not just this flight but the last few SW flights I've had to SNA and SAN as well and it's not just me. I've informally surveyed my colleagues (business and leisure travelers) and these feelings are consistent. The tickets are similarly priced to other carriers and the seat assignments make boarding slower. The free luggage and free ability to change flights is still a differentiator. You lose that and there's virtually nothing special left.

Overall good experience...exception: very cold temp in teh cabin.

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.

Delayed for no reason at all originally. Then they said it was due to weather conditions. Communication between kayak and Southwest was terrible because both displayed different delays and departure times for HOURS throughout the day. The plane then had technical issues which delayed us from taking off even longer. Didn’t actually take off until 11:45pm when the original departure time was 7:35pm. I didn’t get home until 1:30am the next day. I was exhausted and pissed off. I am not confident if I’ll fly southwest in the future or use kayak to book.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

attendents were rude and the boarding was disjointed and poor

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

The plane was so old. I paid a ridiculous amount to fly business and there was no internet for six hours! This can't be happening in 2026 and especially in cross country flights where there are a high volume of business travelers.

The food could have been better and the entertainment could have better movies or streaming.

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

Bag got checked but I thought one personal item was guaranteed.

The seats are very small, that is all the staff did a good job.

Seats are getting smaller and smaller. In flight movies are poor compared to other airlines. Food is mediocre.

My flight left Honolulu EIGHT hours late due to lack of flight crew. This was the second time in 2026. The first class staff were excellent ... personable and friendly. The food was okay ...

The food in first class has taken a big downturn

The flight was delayed and gate changed so that was not fun and the flight to Dallas from LAX was very delayed on Sunday. It was just not a great experience due to the delays both ways.

Nothing available at the assigned hotel as far as brush, toothbrush, etc after forced layover with bags that departed

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

extremely tight seats. seating next to a large person makes the space very uncomfortable. The crew is not very friendly either.

The flight was 3 hours and 40 minutes late. The communication around the delays was awful. I fly this route regularly and it is always late. I don't understand it. The flight attendants were not friendly and were generally loud. This was an overall bad look for American Airlines.
