Terrible, decided to delay our flight since another flight require a flight captain

staff and crew were great but the flight delays for the last few flights are insane. After a long day of work and you will get a notification of flights delay is not the message we want to see. And for some reason it keeps happening often this year.

I love southwest. I can not wait until all the planes convert to the upgraded planes. I love the charging option and the newer seats. Thank you from a very loyal Southwest customer.

My return flight was much better than the flight there! I paid for seat to Veagas but not the return. Thankgoodness they assigned me a seat with additional leg room as I have back and leg problems. I really appreciate it. With the flight already being super expensive due to gas prices and having to pay for bags (now) I needed to save some money.

My first flight from LGA to STL was not good. They didn't do service until over halfway through the flight, the internet didn't really work, and the crew all seemed like they didn't want to be there.

We were stressed about landing as our connecting flight was about to start boarding, being unfamiliar with the airport or where the gates were. We exited the plane to discover we were at the gate we needed. We would be getting back on the same plane but nobody told us we could have just stayed onboard. My wife and I were seated on aisle seats across from each other. We asked if there was a way we could sit together. Once we were at cruising altitude they let us move to an unoccupied row so that was nice.

It’s Southwest. The seats are small, the snacks are meh, it’s $50 to check a bag. It’s exactly fine. Could have been better. Could have been worse. It’s not Spirit

They delayed my flight all day but didn't try to reschedule me until all other options were gone. Ended up on a red eye. Not happy. Lesson learned, don't book the last flight from SJC to RDU.

Every single flight I take with southwest is delayed by at least one hour. Unbelievable

When I made my reservation it would have been nice if kayak would have included my luggage. Unaware that I had to pay $45 each way. Should have asked at reservation time if luggage was being checked

It's no surprise that bigger overhead space would be nice, but they are super convenient and helpful with the baggage claim stuff.

My bag was gate checked in Seattle and I was told it would be at the end of the walkway when I arrived in Idaho. It was not and I had to get it from baggage claim. Southwest Airlines will gate check a bag even if they have room for it in the cabin. I like that a lot. Seattle Airport is not that easy to maneuver. Indianapolis is one of the easiest airports to navigate.

Uneventful, which is perfection in airline travel. Everything happened as it should and when it should. Flight was short so no food. I could have used the App to watch something but took a nap.

Stop with the fake cheerfulness and the too often expressed sentiment that all you care about is our safety. Bull…. You use that as an excuse to keep us cowering in our seats. How about you go back to the old standby of telling the truth… like why you overbook, why you are delayed, why we don’t get vouchers for your screwups.

Healthier snack options in first class. Offer fruits, proteins, etc

Last minute change in gate to satellite N a bit of a hassle since I needed a wheelchair . Someone did come and get me to the gate but it was close. Then plane late. It’s hard on older passengers and families to have to trek from one gate to another.

Still seems like Alaska Airlines is not doing a very good job of anticipating the number of carry on’s going in the overhead bins. I was asked to check mine not to find out there was actually(surprisingly)enough room for my small luggage in the overhead bins. In the past, I’ve seen PLENTY of items in the overhead bins that should be underneath peoples seats.

It seems like most of the time theres no room for my allowed carry on bag. People are putting their things in the overhead compartment that belong under the seat in front of them. Getting tired of that!

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

The crew was great and everything went smoothly coming and going.

flight was hot, it was delayed and there was no wifi.

being late for poor reasons, bad chairs, being regulated to a terrible gate in LAX

As an Elevance employee, don't we get priority boarding? Also, I boarded zone 5 and could not get normal carry on in luggage space. There were many Delta employees on the flight and their bags, which were large and could only fit two bags per compartment, got preference over customers so I had to check my bag.

Everything went smoothly, WiFi connection was strong. Time to upgrade the regional planes, we are all on top of each other. No room to comfortably do anything.

The bathroom is disgustingly dirty. It looks like the crew members didn’t clean it on a regular basis. Also, who made the bathroom so small?. I am not a big girl but I still feel very cramped inside. Def unpleasant experience to use the bathroom.

My experience with Delta is always pleasant. My return flight #1426 from ATL to RIC was very delayed with departure and landing. It also took a substantial amount of time for baggage claim. It was already late at night, so the delays made for a very long day. I did not get home until after 12 midnight.

I had a great flight with delta. Plane was clean and the staff was nice, I would fly again with delta.

After flying with Qatar Airways and Kenya Airlines. Delta leaves a lot to be desired

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Deplorable not to have WiFi on 5 hr cross country flight and spend thousands of dollars

We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

It is completely insane to me that first class does not include WiFi. Also does not include lounge access. Port for phone charging did not work. The crew was absolutely lovely, and the food was excellent.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Very uncomfortable and cramped seats. Everything else was okay, the crew members were nice but nothing was exceptional.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Starlink internet made the flight time shrink and I was able to work.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Flight was comfortable- just had to endure a 1 hr delay because of some maintenance issue. Happy that American Airlines does these final checks but just wish they would conduct this maintenance before the flights.

All good. Flight crew was super friendly at the end of a long day

All good. Easy check in and boarding. Lovely flight crew

Friendly crew and pilot. And thank you to the pilot for his smooth landing technique where the wheels don't hit the ground hard - that should be table stakes but doesn't seem to be the case nowadays.

Four hour delay due to late plane arrival- second year in a row on MCO - DCA route. Pitiful service reliability from American. Will avoid in future

Flight was fine, food could have improved (Chicken Enchiladas) and so could the entertainment options on the seat rest (there was none).

I have generally had positive experiences with American Airlines (outside a handful of delayed flights), which is why I wanted to share this feedback constructively. On my recent flight, my travel experience was extremely uncomfortable because my seat mate significantly encroached into my assigned seat space for the duration of the flight. As a result, I was forced to sit partially sideways, with much of my shoulder and upper body extending into the aisle. Unfortunately, my back still hurts from maintaining that awkward position.I recognize that this is a sensitive and challenging issue for airlines and cabin crews to address. Everyone deserves to travel with dignity and respect, and I understand that individual circumstances can vary. However, fairness also requires that all passengers have reasonable access to the seat space they have paid for. When one passenger's use of space substantially impacts another passenger's ability to sit safely and comfortably, there should be a practical solution available.I appreciate the complexities involved, but I hope American Airlines will continue exploring ways to ensure that all passengers can travel comfortably and equitably. This experience detracted significantly from what should have been a routine flight.

The crew was great! The issue for me is the aircraft. The Airbus A32x is just not comfortable enough and the entertainment delivery via personal devices is problematic.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.
