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.

It's a shame that SW was previously my preferred carrier until they started imposing all these fees (luggage, seats,etc) and pulling back on other perks. I only flew with them this time due to time frame I needed to be at destination. Wasn't provided gate info during check-in, Gate info wasn't displayed at airport until last minute, gate info didn't match what SW personnel announced at fate. Kind of a mess.

Haven’t flown on SW in years. Flight was on time departing and arriving. Served vegan butter onion flavored pretzels which were bad. Coke served was in a tiny paper cup. Crew was not engaging. Felt like they were going through the motions. Old plane, tight seats and no leg room.

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

Pretty standard flight. We left late, but arrived early. The wifi entertainment is always nice. The free snacks and beverages are simple, but appreciated. I'm tall and the seats are an issue. I can deal with a short flight, but any longer, I have to find another airline where I know beforehand I have extra legroom.

Awesome experience. No in-flight video or meal. Still do not like the boarding process.

On time, good crew, easy flight. Just like the old days!

1. The internet with T-Mobile didn't work, so I had to pay $8 :( 2. We stayed more almost 40 minutes because our arrival gate was not available

Excellent because of the flight attendant Wendy in first class. She is the by far the best flight attendant I have ever experienced!

Trouble linking to the Tmobile wifi. The legroom on the 737 was fantastic. No more knees touching the seat back in front. Plenty of charging plugs and inovative clips to hold phones and tablets.

First class flight attendants went out of their way to help me with bag of ice to ice my foot (recovering from surgery) which helped with swelling. And helped with leg rest that I couldn’t move.

I ended up having to sit next to a rather large individual who spilled over into my seat the entire flight. My neck and shoulder hurt from having to sit awkwardly for over 5 hours because this person didn't fit in their seat.

On time departure & early arrival made the long day much better

Alaska has been my favorite airline for years, so this last trip came as a shock and disappointment. The seats on the plane were so uncomfortable and seemingly cheap. The person sitting next to me said the same thing. I used to love the in cabin lighting, the purple was so relaxing, it's now gone. The little touches that made Alaska great are gone. I purchased the wifi and it wasn't working during much of the flight, the flight attendants kept rebooting it. I wouldn't have spent my money that way had I known it would be unusable for 50% of the flight. I am bummed because I always chose Alaska over price shopping. I have an upcoming flight back to DC and decided to go with American Airlines. It was a better price and I don't feel like Alaska gives me anything special.

The agents were super helpful. I was traveling with my mother inlaw who needed whell chair assisstance. The help and accomodation from the checkin crew, to the boarding crew and inflight crew was excellent.

It departed an hour and a half late because the crew got in late the previous night due to weather related problems. So we got into LA later than anticipated and traffic was much worse.

Good. I didn’t order food and there was no entertainment available.

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Flight was delayed for about an hour but overall good experience

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

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).

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Short. Nice quick flight, appreciated after Munich to DC leg.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

the seat has a problem. the back had a hole.

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.

Crew tried to accommodate late arrival due to late departure

I injured myself during my trip. The staff of American Airlines were very compassionate and empathic. They took additional steps to make my experience easier. Thank you!!

There was no ground crew at HSV gate when we arrived. The were busy with another arrival. We had to wait 20 mins for them to arrive and direct the plane to the gate. It took almost 45 mins to get my luggage. The luggage belt had 3 flights bags on it and the other 2 luggage belts were not being used. It looked like there was only 1 crew serving .3 arriving flights.

Liked: staff, no delays, Could use some improvement: Food, comfort, cleanliness, lack of chargers on the DCA -> DSM flight

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

Flight was delayed which isn’t the airline’s fault, but the communication around it was terrible. I left the lounge to show up at the gate to board at the time in my app, and the flight in front of mine was still boarding and the inbound plane hadn’t even taken off yet. Delays were slow to show up in my app. Improved communication could have let me have a more pleasant experience in the lounge vs waiting 1.5 hours at the gate.

Wifi was good on the flight from DCA to Dallas and terrible on the flight from Dallas to Tucson. The forward head in the flight from Dallas to Tucson was putrid smelling entirely urine soaked. The flight from DCA to Dallas was delayed by almost 30 min with a plane change.

Sat on tarmac at arrival at DFw for more than 30 min waiting for a gate.
