Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

It was nice to be on a legacy airline, people try at least.

I travel frequently. The flight was late again... KLM should really try and be on time

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

I think the seats on some of their planes are uncomfortable. You can be ok on a short flight of two hours but no more than that. The delays, and also the refreshments on the plane were not enough.

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

Not sure why JAL partnered with American Airlines because their service is no where near similar. Flight attendants were not friendly and didn’t smile. Food was horrible…

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

I wish the flight attendant was a little bit kinder

The food wasn’t great and it would be nice if the airlines showed documentaries about the countries we are flying into.

Disappointed everytime. The app doesn't load the boarding passes. They have lots of agent that seem to be busy doing nothing with a long line waiting to get paper boarding passes. Food choices are poor. Entertainment is less than entertaining.

Horrible experience. Nothing to give to kids to keep them entertained.

I think I have bruises on my kneecaps. Do the seats have to be so close together these days? And if they are so close they really shouldn’t recline. I think when the gentleman in front of me reclined, the back of his head was on my chin. That being said the crew were always caring and polite, and the flight was on time and very safe. So I’m grateful for that.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

Not connecting flights. Missed my flight from Dublin to Liverpool because I arrived at Dublin one hour too late. For this mistake, they offered me a flight from Dublin to Manchester. Thats great and all, but I waste time and money to commute to Liverpool. Be sure to check the time of your connecting flights, because they sure don’t when they sell it to you

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

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.
