Southwest's seats are the least comfortable I have ever sat in.

4.0 OkayDavid, Aug 2025DTW - STL
Read more Southwest reviews

Southwest's seats are the least comfortable I have ever sat in.

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.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

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.

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

WiFi did not work. For as outrageous as these flights cost, when they’re advertised with certain services/ features they should be in working order

My experience on any Delta flight is always overshadowed by the time Delta removed me from a flight for no apparent reason.

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

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Boarding in Amsterdam is always chaotic. KLM/ Delta has not streamlined or made it efficient as it was boarding in Detroit . The food was mediocre The crew was unfriendly and more focused on getting things done quickly rather than service with a smile .

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

Coach seating is debilitating, neither my husband or I can walk the following day

Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

Sat on the ground in Cincinnati for 50 minutes before deplaning

Flight from Miami to Lima was very good, like the free WiFi to get movies and TV.

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

They should have MSNBC available on board. A 4- hour flight should provide more than a cookie.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.

No food offered, just chips. Crew was no nice. I had to Stand up and ask for a drink. Even for a midnight flight I have had better experiences from another airlines.

Was not able to watch most shows on the entertainment site. They would not load

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

On Wednesday, July 30 we were in mid flight from Manchester to Charlotte and we turned around because the right engine was malfunctioning. That was the last flight out of Manchester that night. I was rebooked for Thursday, which became a weather event Friday. There were no seats left on the flight from Manchester to Charlotte. Consequently I didn’t leave Manchester until Saturday morning and we flew to Chicago so to say the least my scheduled flight and return to Iowa was three days off and it messed with my business schedule. Consequently cash flow. I would like some sort of acknowledgment of this event.

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

flight cancelled after 2 delays. left us sitting in JFK at 1am. no customer service to assist rebooking.

To not have food or proper snacks on a 5 hour flight was the worst.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

There were mutliple delays. There was inconsistent, delayed, and poor communication regarding the delays.

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

I think the staff was nice. They took time to explain safety protocols. Boarding was great. They started early and our flight left a little early which was convenient. Having free games to play would have been better

One restroom was unavailable/closed on both routes, going to Charlotte and coming back to Detroit a week later.

it was a quick trip. seats aren't that comfortable but because it was a quick trip it was ok. You need to have an N/A in your rating as I didn't have any food or entertainment so the only thing I could do was score low.

Not very good because of an almost 3 hour delay for an hour long flight.

Departure was right on time. The Orlando base crew from Atlanta to Puerto Rico was the BEST. The return flight crew was OK.

I paid for streaming wifi and the connection was poor.

As my first time on Spirit, I thought that it was good.

Bad experience. Unhappy with the changing of flight times and one particular flight attendant (Bartholomew) on our flight from Orlando to Detroit. Traveling with a large family of 7, including our 18 month old, can be arduous but when the airline changes your flight time from landing at 9:30 pm to landing after midnight, this becomes much more difficult. When our 18 month old was predictably over tired and fussy, my wife and I tried to move to an open row so we can console her more effectively. The flight attendent rebuked us and said we could not sit in an exit row. We were not planning on sitting there for more than a few minutes but just to have space to console our screaming 18 month old. Spirit did not allow for a family friendly trip. Likely will be choosing a different airline next time.

It was smooth and easy. The only real negative was it took over an hour to get our luggage after the flight

Pl meed tp make proper accom for all pets and owners by placing them on a section to accommodate human animal allergies and give up a few seats YWS ACCOMMODATIONS SHOULD BE MADEBY THE AIRLINES and not pushed off to another paying customer that has to sit in fear or by being touched by someone elses animal.
