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

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Oh my god! For an13 hour flight they serve you food just one time. Also don’t be thirsty they give you a little small cup of soda to drink. They seem like their goal is to feed you one so they don’t have to be bothered with you. It quite surprise for such a long flight there are several times to eat at least three and the food was well lackluster. The food and lack of offering drinks which were always hot no ice provided.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

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

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

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

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

The most horrific experience we had with the airline that we had in our life Everything was substandard at best. For just one hot tea they charged 4 euros We paid for Lufthansa months in advance ,to get there they didn’t have us in record and after 4 and a half hours layover we almost we got one seat at the first row and one in the back of the plane On top of that our suitcase was seriously damaged and it’s unusable. Here we are halfway around the world in foreign language having to fix this on our vacation time Would you kindly and quickly resolve this matter

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.

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. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

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
