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 !

Southwest was greaat! The most expensive but the least upsetting for those we were flying to see.

I was supposed to be on a later flight. When I showed up at the gate, the woman working there was extremely helpful getting moved up to this earlier flight.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

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.

Wi Fi was horrible kept cutting out the whole time and too expensive

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.

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Kind staff. Snacks are small but that’s the new normal.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

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!

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

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

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

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.

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

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

At least it was a short flight. Greyhound with wings.

Our flight got changed and/or delayed 8 times before we boarded.
