Airline reviews

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

It is southwest seat was ok. Not the most comfortable seat

Plz don't take away free bags and free seating

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

It went well. Plane wasn't full. Will be great when assigned seating is in place

Excellent experience. WiFi worked on this leg of My trip

Flight was great, but golf bag never made it until later in the day. Even though I had a nonstop flight it was placed on a different one. They made it right with flight credits and I was able to get it the same day.

Delayed 4 hours due to mechanical issues. No mention of compensation for being over 3 hours late

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

this crew didn't care much. bumping carts into seats more times than i care to remember

Everything was fine except the entertainment was not working for half of the flight.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

The flight was comfortable with the exit row and great service

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

The food and sitting need improvements. They were extremely bad.. If you choose to recline, there is no room for the passenger behind you. This is one of the worst sitting arrangements that I ever experience. The aircraft was not properly clean before boarding.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

I didn't like that my paid for seat was changed 2 hours before my flight.

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Bigger seats. Board back to front! Disembark front to back!

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

Service in first class no longer exists on American Airlines .

My seat was very worn. Otherwise I had an excellent flight

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

I was 2 hr arrive in the airport and 45 min in the line . After take to my turn . The agent tell me I’m later . I can not board . So my vacation was going to the floor . Just for their bad customer service agent in the airline

2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!

It was a no frills flight. Would have liked to be able to charge my device

Seats were extremely uncomfortable and it was very hot on the plane.

Early arrival. Great landing. Pilot updates. Too cold in plane.
