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!

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

Great experience and In love flying in and out of Provo airport

It was pretty good. Only thing that makes our boarding uncomfortable was, that we had to pass TSA at terminal 1 and after that walk 15 minutes to terminal B, because bus was insufficient to take so many people and waiting time for the bus was more then 1 hour.

Breeze was good but the sandiego airport had traffic and waiting 1 hour in the plane till take off

This was my first time flying your airline and it was okay. The people were nice but I am not used to all the add ons and no movies or even water. But I knew it was going to be that way. I think I prefer paying for the extras to be more comfortable.

Check in was a breeze. Crew was amazing! The two seater had more leg room than the three seater. No snacks available, only for purchase. No internet available, only for higher paying ticket. booking through a third party was misleading - purchased with carry-on, but it did not really come with carry-on.

the flight was significantly delayed. Not much was done by the airline to compensate passengers

Southwest has been a nightmare. Delayed flights, missed connections, systems down. Never again am I flying southwest.

I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

3 hour delay. Had to change plans and was still delayed.

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

The flight was delayed for almost an hour. We sat on the tarmac. There was no announcement. Not by the pilot or the crew. And for some reason, there was no beverage service, so even though it was a short flight, we had sat on the tarmac and the extra hour delay made me understandably thirsty. Water would’ve been nice if they had offered it. And for the first time, I forgot to bring my own water bottle. Reminder to bring your own water bottle because you never know if you’re going to get a beverage.

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

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.

Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

Flight delayed four separate times. I’m now one hour hours late to landing.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

One of my checked luggage was damaged. Cracked on the top by the handle.

I have been flying united for a long time but now I’m done

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

Multiple delays and made us miss the connecting flight and lost our bags

Little communication with passengers after sitting over 1 hour for a maintenance issue Then we had to deplane- no crew communication Poor gate information after deplaned WiFi would not connect AT ALL

Flight attendant made the flight very enjoyable. He was courteous and gave great care to the passengers

Not good. Flight crew, was not friendly and just shoved stuff at us. Not the way I like to travel.

Aside from the little delay, overall was flight good. Made it safely. Thanks!

Over the course of 7 months of travel, I can count on my hand the number of times the flight has departed on time. Majority of the instances have been related to non-weather reasons. Would not recommend flying this Airline

The plane was spartan, the seats not that comfortable. It was like flying a super low budget airline. They charged for coffee!!! I have never, ever experienced that before.

I had no problems but the changing of planes that I was supposed to be on was confusing. Maybe it would be helpful to let people know your flight changed. Not everyone understands airports or how flying works.

Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.
