On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

they made me check my carryon. There was space in the overhead bins.

It was spectacular. I had basic Economy and was given so much space and their seats lean back so far. Staff was superb, food was superb, everything was superb, Finnair is Fantastic.

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Cold air blew constantly on my legs almost making me numb.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

Cabin crew were great. Seats are criminal for tall people

Flight was delayed 1.5 hrs due to problem with a previous flight to mine; I was informed appropriately via Text & Email, however, website did not keep up with messages sent by nearly an hour. When checking-in warm & friendly reception at check-in desk until female Air Canada Rep noticed my flight number and instantly pivoted to a condescending & sarcastic comments about getting my bag checked in since I’m running so late; then tone instantly changed again few minutes later when she muttered, “Oh, they’ve delayed it” another sign systems & worse front line staff, not fully informed or simply not reading their flight status updates. Flight crew were very friendly & did a great job trying to make up lost time due to the delay.

It was great, love the experience and will definitely recommend 👌. Communication was great

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped

It was great to check carryon luggage at no charge when there was no room for ours. A hidden benefit of having low-tier tickets. Also great to stay off plane as long as possible. Airline gave us seats we wanted on this last leg, again at no charge.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

The late departure Of two hours waitresses, immature, and gossiping

Crowded plane but it flew on time and had friendly staff

We had a good flight, service was good and lots of leg room. Service was good and the staff were friendly.

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.
