Airline reviews

Had a long layover in rainy Chicago. The staff were attentive - my husband needed a wheelchair due to a recent fall and unsteady on his feet. They are wonderful for those of us who need a bit of extra care. My only complaint was discovered upon unpacking our suitcases at home. One (we had 3 carry on size and one just a bit larger) had water damage to everything inside. All the clothing (just happened to be the case with the clean clothes) were wet. I know it was raining, but why would items inside be wet? The paperwork packed in this case was damp with ink running. There were momentos from our 10-day European vacation that I was hoping to scrapbook - but alas, they will be scrapped - too damaged to keep. The boxes of French chocolate were damp on the outside. My expensive camera now has a cracked screen and a Gaudi tea-for-one was cracked - even though it was packed in clothing. I know it happened on this flight as I repacked all four suitcases before leaving New York in the morning. My first unhappy experience with luggage at Southwest.

Southwest has a serious issue with keeping their passengers in the dark about delays. They also appear to lack the necessary crews to deal with any sort of hiccup in their operations. The way they run their day-to-day operations is a joke. You are telling me that a hail storm in Denver, where hail storms are incredibly common, results in hours of delays due to every plane needing to be inspected for hail damage? Understandable, but there seems to be a skeleton crew of maintenance workers undergoing this daunting task. There was no particular order of inspecting planes, leading to some planes only having an hour delay or less in others having four or more just because of the luck of the draw of what plane got inspected with no consideration to how long the respective delay was. The entire time the passengers were told nothing except the fact that there was lightning in the area and the ground crews could not load the bags. This always happens that Southwest will incrementally delay a flight with no information given, leaving many frustrated passengers fuming once they find out that their flight is canceled. Don't make people wait around for hours at the airport giving them no information, just to keep them on the hook and prevent any action from being taken by the passengers in terms of finding alternate routes of transportation or accommodations for the night. How many hours of people's times do you think you waste by operating like this? How about having a fully staffed crew in one of your busiest hubs that is famous for severe weather that can effectively deal with a situation like this, or how about having planes on standby to quickly replace in case something like this happens, like all the other major airlines do. This is just like the Christmas fiasco but on a Denver scale, but again this is literally just from a single thunderstorm going over Denver in the spring. I'm glad I've stopped using Southwest as my primary airline and have switched to United. Every single time I fly Southwest, something has to come up. It's ridiculous and I seriously can't wait to finish using my miles so I don't have to deal with your garbage anymore. You used to be so good and I don't know why you thought you could just scrap your quality and expect people to deal with it. Oh, and I walked by someone getting CPR for over 5 minutes in the concourse. I hope he was ok. Southwest needs something similar.

Our flight to Oakland was great bc the plane was new but it was delayed by 15min not bad at all. Over all it was an 8/10

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

The flight itself was good. Delays were the problem. Original flight was scheduled for 8:10 pm. Got notifications all day -- actual time is 8:40; then 8:25; then 8:35; then 8:45. Then once I get through security, it's actually 9:35.

Crew was great but because of fog they diverted us to Ontario instead of our Santa Barbara destination. Instead of cancelling the flight as soon as we landed in Ontario, they instead held us in Ontario for almost 4 hours before cancelling the flight. I had to rent a car in Ontario to get back to ventura on time to get an elderly relative his medication and take over his caretaking… otherwise if I had taken the buses you offered from Ontario I wouldn’t have even arrived to Santa Barbara till at least midnight (according to southwest airlines employees at Ontario), and then would have had to drive back down to ventura. At least renting the car I could get up to ventura by 10 pm to take care of my loved one.

Boarding was quick. The flight itself was good. However, no charging ports for cell phones. Also, the food provided was just a few snacks. For a 5-hr flight, I would expect at least a sandwich.

Everything was great except for the in-flight wifi that wasn't working.

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

Everything was very good. I will fly Southwest again soon!

I like the big picture of the Eskimo on the tail of the plane.

Barbara at JFK terminal for Alaska was very helpful in retrieving our boarding passes for our connecting and quite pleasant!! Thanks

Being seated next to the engine was awful! I was nauseous the entire trip from pre-take-off, flying to landing. The engine vibration was very strong!

Everything was great but there were no entertainment options available.

The crew was the best I’ve had the experience of flying with. A misbehaving child was making things difficult for me with bopping my tray table, taking my snack, and continually tapping or bumping me. The crew quietly and respectfully moved me to another seat, and thanked me for my patience. They couldn’t have been more kind. Their professionalism really stood out to me and I am more than happy to leave a great review for them!

I would have appreciated notification that our flight was moved to another gate LAST MINUTE so that we would not have missed it. We got no such notice and had to spend another night to catch an available flight in the morning, which was huge inconvenience. We will never fly Alaska again.

Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

The plane had to sit on the tarmac for 45 minutes once it had landed. Not Alaska’s fault.

The airline was way too cold. We were freezing, I don’t know if that is normal. Overall it was pretty good flight. Always flown Alaska Airlines and I am not changing.

Mediocre is best way to describe. Bare bones narrow seats, Dirty pulldown tray, unfriendly cabin crew who were in a hurry to serve tiny drinks and tiny snacks. (Compared to much better Hawaiian Airlines experience, .. no comparison!)

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

From bag drop to boarding, it was great. In-flight is a little different. The seats were a little uncomfortable for that long of a flight. The rest of the cabin crew except for Eva was wonderful. Eva was not friendly at all. I've had to personally encounter her twice in-flight. First time was when I had to go to the lavatory in the back of the plane, and since it was the first for me to board such tiny plane, I didn't know we were using the crew toilet. She was giving me an attitude while telling me where and how to open it since it's not the regular push to open type of door. The second one was when I had to throw trash then use the lavatory again. I asked where to throw them, and unfortunately she was the only crew in the back doodling on her phone, she had to point it out to me with an attitude then told me to wait on the carpet, which I understand because I didn't realize that, but she could have been nicer. After all, I'm a paying customer, and assisting a passenger who isn't knowledgeable about the aircraft is one of the things she's there for. The rest of the experience and crew from bag drop to in-flight were excellent except for her.

It took an hour to get my bag after landing. Not exaggerating

We flew halfway to our destination (NYC to Burlington) and turned around due to a mechanical issue (landing gear wouldn’t retract automatically). We turned back to JFK for JetBlue’s benefit as we landed safely at JFK and could've just as easily landed safely in Burlington on our Christmas Day flight. Instead the company directed the crew to return the plane to more easily service the aircraft. The passengers landed 3 1/2 hours later and JetBlue gave each passenger $50 for the trouble. Hardly fair compensation to be separated from family on Christmas Day.

I had a horrible experience with TSA at the airport. I had to go through TSA several times as there was some issue each time with a piece if clothing I had on. It was so busy & chaotic that I ended up forgetting my Apple laptop at TSA. It’s been days & I can’t get through to anyone to get useful info on how to get it back. I’m very angry because contacting lost & found shouldn’t be this difficult. Employees should know what is going on at their place of work. It seems no one knows as everyone’s answers are contradictory, or you can’t speak directly to anyone as the calls are automated. Very upsetting.

No food/drink were offered. There was no Flyfi service. The screen size & quality were below JetBlue’s typical standards. The flight was delayed by an hour.

Everything was good instead change the gates! I missed my first flight because it was changed the gate and I didn’t know!

The new seats JetBlue uses angle downwards, so the entire flight you are sliding forward out of your own seat. These seats suck!

I was shocked flying to El Salvador that they only give you water. Everything else you have to pay for. There is no wifi or entertainment and it’s an international flight. At least back in the day they had tvs on the plane and everyone watched the same movie. Also seats do not recline, even comfort or plus.

I did not like anything, first time I use company and for sure it will be the last time, they charge for simple operations that any other average airline wouldn't charge.

The good thing is the flight was on time and the crew was really nice. They can work better the arriving with staff

The inflight entertainment did not work on a 6 hour flight The cel phone chargers did not work There was a 45 minute wait for the luggage to get off the plane.

Seat space was terrible no food on a six hour flight

This is the Spirit of Latino travel. And don’t even get me started on customer service.

There was no bag included in the reservation. The price was double. Not properly advertised

It is better at the jfk than my home country. It was very easy and everything was on time.

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

They could offer free food and drink like other international flights.
