Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

My experience was okay I changed my returning flight and I was charged extra money which I dont think should be the case, especially because I experienced small delays from my going flight. And many flights were either canceled or delayed after my original flight time. I believe some customers should have the ability to change flights due to certain situations

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

Your computers were down and took a long time to check baggage

Flight attendant skipped about 6 rows for drink service. I got a side eye when I asked for a drink - like it was an inconvenience or my mistake. He shouldn't be on a flight if he doesn't like his job and doesn't have customer service first attitude.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

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.

Delayed departure, 30min. but arrived nearly on time. Crew was reassuring.

The flight was delayed at the very last minute and no information, both of my round trip flights were delayed at least the BNA to Boston was informed earlier but the return one was horrible

While it wasn't the crew's fault, it was a frustrating flight. We sat on the runway for 2+ hours. Both of the flight attendants were excellent and did a great job checking on the passengers. The pilot did keep us informed about the wait. I appreciate the crew apologizing for LaGuardia airport's backup.

Internet didn’t work for this leg either. The seat was fine but didn’t have seatback screen, which I knew when I booked it. The biggest letdown is Deltas new policy on beverage/snack service not being served for flights less than 350 miles. I know this is a cost cutting measure, but how much does it really cost to give a drink and a snack for inflated airfare? I really am surprised that with Delta Comfort they don’t provide beverage/snack service given these seats cost extra to purchase. Really need to reconsider this, even if it’s for the Delta Comfort and above.

The flights are constantly late anymore, and they won't even give you a glass of water on the plane. For years, they were able to do a service on this flight from Atlanta to Knoxville and Knoxville Atlanta now they say it's too short of a flight. You can't even get a quick drink of water.

Should never have had to go to Detroit from Orlando back to Tennessee!

My flight was canceled on Sunday. Rebooking took three hours. Had to pay for accommodations another night. New flight was delayed for 5 hours, all that was sent was a 12 dollar food voucher, which doesn’t tell you how to use it. Then when we landed we had to sit on the plane for an hour before we could get off.

Same experience as the flight from Norfolk to Atlanta where people are boarded in zones that don't make sense. People behind you on the plane will get on before you and they take the luggage space on your row.

Smallest leg room I've ever had on a plane.

Seat would not recline, and charger did not work. Person in front of me reclined before we took off and left it reclined when they got off the plane. Nobody ever told them to put their seat in upright position....which meant I was somewhat trapped in my window seat when deplaning. Another passenger had to go to their seat and un-recline so I could get out.

The TVs on the plane were all broken and inoperable. No snacks or food were served. Plane was very old and uncomfortable.

It's fine but Newark to Nashville was too long

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

We had excellent customer service despite the chaos at George Bush airport in Houston!

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

For some strange reason I was put in zone 5 for boarding even though I had paid premium price for a premium seat right behind business class. This must have been a flaw because everyone else around me in the same zone (row) had been placed in zone 3.

Would had been nice to see a movie without having to pay to watch

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

The plane had originated in Las Vegas at 6:30 in the morning and flew to Moline where we boarded. The flight left around 12:30 PM and there were no boxed snacks available and many of the alcoholic beverages were unavailable. I would find it hard to believe that that many of the passengers coming from Las Vegas at 6:30 in the morning, drank and ate that much of the items. I can only come to the conclusion that someone failed to stock the plane for the round-trip. This is a huge revenue failure for the airline and disappointment for the passengers. The flight crew did not seem happy to be there and did not engage with passengers. Allegiant you can do better.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Posted a 20minute delay but didn’t delay at all. Caused boarding issues and confusion. Also, didn’t release baggage. Took over an hour and 20 minutes to get luggage.

Flight was good, boarding was a breeze, flight attendants were friendly and professional. There was a medical issue with another passenger and the crew handled it in a calm and professional way.

Great seat space. However food and drink prices outrageous. Jabbing to pay for a carry on bag or stuck paying at the gate too much.

desk agent in sioux falls is rough .needs customer courtesy training

I went to lower my tray table and it was very nasty. Looks like some one had left some food on it and then just closed it up.

I didn't like anything about this flight. The only reason anyone drinks Jack is because you ran out of Woodford. You should know to stock more Woodford. When you wait of first class hand and foot from the minute they get on the plane 5 feet from me but then start service from the rear of the plane so main cabin plus gets the scraps, that's how you get people to stop flying your airline.

The flight was normal, until it wasn't. I fell asleep after boarding, woke up still on the ground, the flight couldn't leave the gate due to mechanical issues, including a/c failure. The air felt thin, similar to high altitudes, not sure if that's why I fell asleep but it happened to the passenger next to me too. They hooked us up to external air but it didn't seem to help much. They finally decided to deboard us after nearly 2 1/2 hours. We reboarded about 45 minutes later and landed about 3 hours 15 minutes late. Some passengers got water or something but I was never offered either. Honestly, with that big of a delay, they should have provided full service to make sure their sweating passengers had fluids. Yes, it was a typical over 90 degree day in Texas. The lady in front of me said she was getting a heat rash. It was rough . . .

Flight was delayed and so much of inconvenience related to the gate change.

Flight was smooth and on time: however, this flight was filled with advertising. We got it over the speaker system both when we took off and when we landed. Flight attendants were handing out sales flyers when we landed. It was not a good look.

The flight was delayed almost three hours. I understand delays happen from time to time, but this flight was delayed no less than 10 times. I wish the amount of time of the delay was more accurate, versus delaying in 10 or 20 minute increments many, many times.

Delayed by 5 hours and I had to wit in the airport for more than 6+ hours.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Arrived early picked up my bag in a few minutes- great trip - thank you
