3 hour delay. Had to change plans and was still delayed.

3 hour delay. Had to change plans and was still delayed.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

We got exit row seats both flights. Everything was running on time

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Pretty seamless, just a tad bit late in taking off and landing.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

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.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Staff was great! Kind and cordial! Middle seat row 28 seat B has a hump in it. Trays were getting stuck when putting down and up. Good flight

Departure was delayed resulting in me missing my connection. Delta did not autimatically find me another flight.

The seats weren’t reclining even though it wasn’t as exit seat

It was good because we traveled without luggage, carry on only.

I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

I have diamond medallion status and usually we are in comfort plus . We were in main this time ( which was fine ) and my husband wanted wine . I have at least 10 vouchers for drinks that are good for this year and next! The attendant would not take the picture of the voucher as proof and never came back to check as She asked me to pull it up on delta Wi-Fi. Instead my husband just used his Amex to buy the wine . Disappointing!!!

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

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

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

We were upgraded to First Class and it was a great flight

Amazing I love American. I’ll never fly anyone else if I can help it.

I love American. I’ll never fly anyone else if I can help it.

Flight delay and multiple gate changes including a change near boarding time to another terminal, which in DFW is a pain. Pre-boarding delay and also a further delay on the ground after boarding. About an hour and a half total delay.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

Little warm on the plane and delayed for an hour

Tell the crew (when boarding) to yell at the imbeciles blocking us from walking up to scan. I promise everyone crowds around and half of us (most the time I’m group 4) have to push our way through. Your staff is awesome, the public - not so much-

Bags took over and hour to come out. Delays due to wind caused rebooking.

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

Flight was not on time and it was very annoying flight. Keep changing gates.

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

The flights were very uncomfortable the seats don't have much leg room at all and they are pretty hard as well.

It was delayed but the landing was the smoothest in a while that I’ve had.

Second time in 3 days I walked off the plane late. This time - almost an hour.

Everything went well. The flight was slightly delayed however we landed on time.

I've flown two Spirit flights recently - boarding for one was somewhat chaotic, with the board listing the wrong flight and causing much confusion; boarding for the other was very smooth and easy. My seat (for which I did not pay extra) was a bit narrow and without great legroom, but it was fine for a NY-Florida trip and was more than worth the low price I paid. The crew was friendly and one flight landed early and the other was only very slightly delayed. All in all a very good experience.

Had to pay for water if wanted it. Seats are close unless you get upgraded. Flight was fine. Will travel again with spirit.

Your flight crew and boarding area crew need to have microphone use training. They all hold the microphone right up to their mouths, way to close making understanding them almost impossible. The microphone should be held about 3 to 4 inches away from their mouths. This would provide for much better clarity through the PA system. ‘Eating the mic’ DOES NOT work.

It was the first time I flew on that airline and had a very positive experience. Nearly identical to Jetblue which consider the standard of airlines excellence.
