Airline reviews

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

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

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

It was rough. The staff was unprofessional, the choice of on board drinks terrible, it was cramped in space at every airport, they always ran out of overhead bin space so they pressured people to check bags for free or we couldn’t leave on the plane— so I did check my bag to help, and they nearly lost my bag. My bag did not arrive on the luggage belt, another man on my flight and I had to waste our time going to the baggage office to search for our bags. I would only fly southwest again if it was my last choice. Also, my flights were consistently delayed over and over again— at one point they straight up told us we were waiting for the pilot to arrive.

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

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

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

A little bit more leg room in premium economy. I am 6’4”.

It was a good experience. I do wish the seats were roomier. Also, I did not like being charged for my carry on bag

Exceptional take off and landing in snow and wind…thank you to the well skilled pilots!

I liked entertainment system being downloaded on my iPad. The selections were limited but I appreciated being able to use my own screen. The flight was just fine. My only issue was both terminals being far from the main airport. Especially stoning at LAX near midnight and having to wait for a bus to take us to baggage pickup. Very inconvenient.

Just fine but comfort is always an issue since the seats are so close

The Flight was fine, the staff treated me well, the flight got delayed over 5 1/2 hours for maintenance issues....but it worked out OK,, they were very apologetic about it, and it is better to not fly if there is any issue than endanger peoples lives, so in reality that was a good thing, It did cost me extra for parking because I went beyond the time I had purchased for parking at MSP. But all in all, Good flight

I did not take this flight because the reservation made by Kayak was wrong! Kayak owes me a trip from Minneapolis to Duluth.

When I got to the airport in Seattle, they told me the flight "did not exist". Kayak reserved me a seat on a flight that did not exist. This is inexcusable. I was able to change my reservation to a flight that actually did exist, but the flight was later and then I didn't make it in time for the next leg of my trip from Minneapolis to Duluth. Kayak owes me a trip from Minneapolis to Duluth, and a big apology for messing up my reservation.

The plane was freezing cold. Asked for a blanket and there were none. Was told twice that the pilots would warm the plane and it never happened Worst experience flying ever

Multiple delays because they screwed up on the crew schedule and had to wait for over an hour for more people to come.

The Wi-Fi was off, the arm rests are hard plastic.
