Flight was delayed at airport with large backlog and WiFi was spotty

I don’t like mushrooms and that’s all they had with pasta

I Love Delta but one of the flight crew training in courtesy snd hospitality.

Could have been on time and not missed my connection

Wifi on this flight was very sketchy and not available for most of the trip.

Audio Visual Equipment lacking content and features. Could not connect to noise cancellation earpods

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

No snacks not been water was offered I fly weekly and have to select Economy or extra comfort per business rules but will choose American at least they offer mid seat class passengers water. on short flights. The WIFI was awful on the plane as well. The thing I can not figure out is why you treat business class people this way we spend more money that your one trip first class passengers cumulative than others maybe look at the company name of the people flying and treat us better as there are thousands of us flying weekly and choose what airline we want to select.

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Lost luggage, they need a baggage service representative available all times in Atlanta

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

The staff was so kind and very helpful. I had to use handicap wheelchair services and was so thankful for how well they treated me during my whole trip. Thank you so much. Jessie took time to explain his service and what part he played and how others was going to be available to help. The flight attendants was so helpful in helping me get to my seat. Made me want to plan my next trip with United Airlines. I usually use Delta.

WiFi never works on any flight and the attendants can never get it to work. You would think paying so much for business/first would give WiFi. Also, the food in business is really poor these days.

DFW notification of changing the gate notice was an inconvenience.

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

The flight was delayed 4 hours, and when we finally boarded, they told us that the fuel was only just then checked. So, we waited even longer to take off.

Flight was extremely hot and they made us check our bags when the space was nowhere near full

The only thing to like was that we eventually got to our destination

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Our 8:45 am flight kept getting delayed. Boarded after a 2 hour delay only to be taken off the plane again. At 12:30 pm, we are told there was a new plane and we had to change terminals. Flight was delayed again to 1:50 pm. Eventually boarded again only to be on the plane for over an hour. Flight finally took off at 3:30 pm. 7 hours after original scheduled time. To top it off, couldn’t even get coffee on the plane due to turbulence.

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

The agents at the gate were rude. The stwards were pleasant. The seats were comfortable. The tray table had crumbs on it. A passenger talked constantlt and very loudly for the entire flight annoying many passengers. The stewards did not ask her to speak in a lower voice but my travel partner did.

The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.

It makes no sense for several types of drinks to already be out of stock in the middle of the flight.

I have a walker I need it to get from the plane to customs and baggage claim. It had a huge orange tag on it saying it should be given to me as I got off the plane. It was not and the flight staff didn’t know where it was—both on my flight to London and on the return. In It was very frustrating

Late lights, lost baggage and cramped seats. Did not feel that lost baggage was a priority. Communication was slow and often unclear.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Besides having a LONG layover in Philadelphia to begin with, our flight was delayed and left late. We spent 7 hours in the Philadelphia airport after being in the air 7 hours from Portugal to Philly. It turned into a 24 hour day of travel which was exhausting. I know you can't help weather but our layover was difficult as my husband is handicapped. The staff was EXTREMELY helpful with his wheelchair tho!!

The decided to just remove our booking without telling us. It ended up costing us thousands

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.

I have to depend on wheelchair and that experience was bad. At Heathrow as well as Atlanta. They said we will have to wait till last passenger since there are twelve of you. If they knew why couldn’t they make proper arrangement? Even at the baggage counter we were dropped saying someone will come and couple of us waited almost half an hour again. Felt so sad and helpless.
