The WiFi worked for entertainment but a nearly 4 hour flight should have personal tvs

Generally very good. Waiting (due to de-icing and traffic) in plane to take off was a put-off. But it's not the airline's fault. I find Airbus more comfortable than Boeing.

Lot's of good food and free entanglement made the trip pleasurable and fun.

The food was terrible, worse that what you get with UA, an already one of the lowest standards to beat. How cheap one could be, providing that kind of junk food in first class. Unbelievable! The seats were not very comfortable either. And there were no screens either, not that I cared much but for you to know.

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

Great flights, little turbulence, pilots kept stewardesses seated & safe, all staff friendly & professional

There is no entertainment on the plane. The snack is minimal. The crew was nice and professional.

Smooth flight, on time despite Captain’s forecast of troublesome weather conditions.

The aircraft was extremely warm the entire flight. After we landed we were stuck on the plane for another 45 minutes without a gate to deboard from. The smell of exhaust from the engines in the cabin along with the heat inside the cabin made the flight uncomfortable.

in-flight wifi was not working well. also the cabin temperature was a bit hot.

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

The flight was flying with 30% capacity. The flight my seat from preferred seating to back of the seat. Even though i can understand that this was to balance the flight weight. The flight attendance decided to do the serving near my seat and in the middle , their noices woke me up from sleep , when i realized that the service has ended and when they were going back asked for a coffee, for which they answered they have completed teh service in my location. That really upset me as they woke me up and also rejected the coffee i asked. I ended up landing with a headache, thanks to the crew that screwed up my travel

Delayed. Hot. Passenger next to me was so large I couldn’t move.

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.

The boarding process doesn't make sense since some people that will sit behind your rows are boarded before you and then they take up the luggage space above your head. I then have to wait for people to get off the plane before I can go back to get my luggage.

Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

The flight went very well, but the flight attendants didn't serve and food or drinks other than 1st class due to rough air but to be honest it wasn't that bumpy and I felt that they could've at least offered water and coffee perhaps. Also serving 1st class only is a bad look. I've been in 1st class many times and I would've felt that if the turbulence was too rough for the main cabin, it would be too rough for 1st class too.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

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

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The crew was excellent and overall the flight was good. No complaints.

I didn't end up taking this flight. I got up at 4am for a flight that was supposed to board at 6am - at 5:55am you delayed the flight to 10am. The airport is under construction so I switched to a later flight as I wasn't going to sit in the airport for 4 hours. They said the delay was due to the crew needing rest from a flight coming in late the night before - if that was the case then I think you should have delayed the flight much sooner so that passengers wouldn't get up so early and get to the airport to sit and wait.

Never had such a lazy first class attendant. Literally spent 60%+ of the flight playing games on her personal phone making up excuses of why she was unavailable.

The flight attendants and the service is getting worse by the day.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Like all of the flights I took to get down to Dallas. They were delayed

Other than nearly three hour delay for maintenance issues, everything went smooth

Plane from partner PSA was filthy. Plastic needs to be thoroughly cleaned. Really disgusting to look at and wonder about cleanliness of parts less visible.

The baggage claim experience was poor. The plane crew and the AA app said that checked baggage in CLT would be at carousel 7 but the sign at Baggage Claim said carousel 1. The carousel 1 sign had the correct flight # listed above the belt. But the luggage never came. I went to an AA baggage claim office after about 1 hour and the clerk directed me to another AA room that was poorly marked, with a closed door and no obvious way to know what to do. Finally someone opened the door and my bag was inside. The clerk was totally unable to explain why.

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.
