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.

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

Very quick and easy process from check in to deboarding and baggage claim. Crew was professional and friendly. Flight was smooth and on time. Very convenient for short flights.

It was easy and very comfortable! The crew was accommodating and cheerful. I enjoyed myself!

I normally have very good experiences with Breeze. The crew is great, pricing is excellent, and the planes are new and usually clean. This time in Huntsville we were delayed, which I understand can happen, however we were moved from one gate to the opposite side of the terminal and then back again... There was a lot of confusion. Also, my seat had a lot of food crumbs still on the floor where I had to stow my bookbag, so that was a bit disappointing. Other than that, all was good. Crew was great as usual!

Our flight was delayed 7 hours. Due to a change in equipment we were downgraded from "Nicest" to "Nicer," even having to pay for a soft drink. Disappointing. To Breeze's credit that issued a $100 flight credit. A refund would have been more appreciated.

Lost my luggage and terrible experience with customer service trying to track it down

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.

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Can not wait for seating change to reduce the amount of pre boards - it’s disheartening the abuse. And then then deplaning

Flight was delayed more than 2 hour do the scheduling issues and then some confusing weight and balance matters, followed by a miscommunication with the tower on which runway was going to be used based on the airplane weight. All these things should have been figured out in advance. Instead of arriving at 12:30 a.m. we arrived at 2:30 a.m. very difficult to find a taxi or other transport at SFO. Luggage was delayed. An extension of an unpleasant flight day

The crew was fabulous, outstanding, friendly, attentive and just great, really made my flight one of the best I've ever had, thank you southwest crew flight #474, from Los Angeles to San Francisco on April 2,2024

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary

We sat on the runway for over an hour before departure. That was unwelcome.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

Excellent flight. On time. Great staff. Clean and crisp cabin.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

The flight attendant was very polite and attentive. The food was good.

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

Long 5 hour and 45 min flight and only one drink service and cookie snack

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.
