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.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

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

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

The pilot greased the landing and the crew was fantastic.

delayed due to weather. Could not communicate with family since the wifi was broken

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.
