Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

I didn’t not like that I could not select my seat and ended up with the worse seat.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

Please see my lengthy description on MSP to Atlanta survey. Tailbone is killing me from old hard seats. Seat would not recline and were not near exit row. Entertainment did not work properly and couldn’t use. No audio and touch screen failed. 3 plus hours of discomfort in narrower seats than previous flight not in comfort plus. Very dissatisfied and deserve comfort plus charges refunds, at the very least, for both my wife and I. The plane needs to be retired. Please feel free to contact me directly for further details.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

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.

The 787 economy was a disaster for long haul. The space was too little compared to 777 or 747. Also the extremely low tray table behind the seat made any dining effort a nightmare. However, the movies were up to date, and the food taste was good, despite of terrible serving process caused by small space.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

0ur assigned seats were given to other individuals when we boarded the plane. We were given new boarding passes with new seats all the way at the back of the plane. The reason given to us was that there were issues with the seats. We found out that there were no issues, and someone else's were seated on those.

There is no food or entertainment on these short flights. Again the wheelchair situation in Denver is nasty. They are short staffed due to cut backs and layoffs and this impacts on travel comfort and ease.

My flying experience with Air Canada was good but the wheelchair situation wasn't good at all and if would be good to make sure that they have the appropriate services available for your traveling passengers.

There was no food or entertainment on this flight. Great flight crew though

All of our flights got delayed. Fll-Montreal delayed due to technical issues. We got transferred to a Fll-Toronto flight, in Toronto flight got delayed 5 hours causing us to miss our connection to Amman. We are now arriving to Amman 24hours later

Flew in Business Class. The new AC lounge at SFO is one of the best I’ve been to with a spacious design and an open air deck. Flight itself was on-time and as expected overall.

In flight wifi that I paid for was very slow and at times didn't work at all.

It has space for legs. Comfortable seats Punctual Some snacks should be served

Air Canada staff needs to be trained in hospitality. Most flight attendants are with attitude. Air Canada needs to carry additional food on board especially vegetarian plates as this category of travellers are on the rise. This is necessary for long distance flights. Blankets are cheap. Seats are not designed well Lower back portion should be thicker. Everytime thr passenger at the back of me took stuff or put stuff in the pocket of the seat in front of them which is my seat, I could feel them pushing or hitting on my chair.

Flight delayed two and a half hours from Toronto to Calgary Philadelphia to Toronto we were listed as standbys !!! Very concerning

Flight delayed at the last moment Hill next day and havé to drag at Hotel at our cost and bec day was again delayed 4 Times because no crée and no pilot

My school age daughter was not sat near me. We left almost an hour late. Therefore arriving late and missing another flight. Since it was not a connecting flight there was nothing Lufthansa could do about it. After the selay in take off and arrival we waited almost an hour for baggage claim. There was zero concern for my inconvenience. I asked if we could insure being seated together on the return. They stated no because we booked through Kayak. I typically love Lufthansa. This was very disappointing.

This flight is always a cramped bus. The gate area was inadequate and announcements were hard to hear. The flight was delayed 45 minutes to an hour by a broken aircraft door, making our total delay from Vilnius 5 hours.

Great seats assigned and comfortable, movies are good, food is delicious, great experience. No delays and they prioritize boarding children with parents which is plus.

they canceled my flight and we’re absolutely atrocious and helping me rebook

My flight was canceled. New flight is 40 hours later and I still didn’t get the flight from Frankfurt to Zagreb.

Great service. The flight was in great condition and the staff was very cheerful.

Check in crew in Charlotte NC was superb. There were 6 of them plus what looked like a supervisor, helping to answer questions and keep things moving. Never saw so many check in crew. Then some of them showed up at the gate later for boarding. Great. The flight was mediocre. The seats were small with little leg room. The screens kept coming on when we were trying to sleep and wouldn’t shut off. I know we paid far less than first class but does that mean we should be shoved in there??

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

Terrible. The flight from Islamabad to London took 3 hours more then previously planned, I missed my connection to Chicago, and instead had to go New York, spend an extra day before arriving at my final destination. The return leg of the journey was similar. The connection time in Qatar was shrinked to less then an hour unannounced, I had to scramble to barely make it to my flight to Islamabad. Terrible experience, never using British airways again.

The crew on this flight were attentive, efficient and friendly. It really made for an enjoyable flight.

The crew on this flight were excellent. They were friendly and attentive. It really made the flight more enjoyable.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

British Airways canceled our plane and gave us a new flight scheduled to leave in only three hours, so we had to drop everything and rush to the airport. The new itinerary only left us a one hour layover in Madrid, which was too short because the plane landed late and so we missed our connecting flight. We were then booked onto a flight scheduled to take off 8 hours later, and were not given any compensation or remedial measures.

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

Despite many attempts to work out a change, neither British Airways nor Kayak nor Chatdeal would allow us to cancel or change this flight so we lost all of the payments when we were not able to fly. Absolutely terrible customer service. We will never use either of the services again.

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.

I asked for a wheelchair. I have a back health condition. I had to walk a lot
