Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Great!! I haven’t had a bad experience with them.

A lot of snacks and provided on request by traveller. Preferred meals which were on their menu were not always sufficient for those who wanted them. We were told 2 different items and offer which we asked for were not offered initially. We rejected the 3rd item given as a substitute for our initial choices which we didn't want and so we didn't accept it. Eventually our initial choice was offered. During service of coffee and tea, the crew member didn't offer us and moved back. Luckily neither of us wanted tea at that time. Crew members must avoid behavior that may be suggestive of discrimination

Online check in and seat assignments are terrible. All 4 flights

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

I use a wheelchair for mobility. Both in my flight from Houston and back to Houston from Istanbul, the Turkish airline staff asked that I claim my wheelchair at the luggage area. On arrival to Istanbul, parts of the wheelchair were in disarray at that time I raised no objection however upon claiming my wheelchair in Houston parts where outright missing. In both occasions, upon arriving in Houston and arriving in Istanbul, I asked multiple times why am made to pick up my wheelchair in the baggage claim rather than at the jet bridge. Getting the wheelchair at the jet bridge minimizes the probability of loosing parts because they can be hopefully reclaimed on the spot. I was told in Houston that a manager turned down my request to claim the wheelchair at the jet bridge in Houston. This is extremely frustrating because a wheelchair is not a set of clean underwear or a toothbrush- this is the way I move. A Turkish Arline staff took my complaint at the luggage claim area in Houston but as of the writing of this review the only contact I have received from the airline is because I initiated a claim rather than her as she told me she would.

Crew members, pilots and flight attendants are excellent. Beside, that, customer service is very lacking in all aspects of Turkish airlines

For me it was a good experience… thank you Turkish Airlines

You need to weight all bags together because we were 2 and we allowed 4 bags plus hand carry and personal items. We trying to saved bag like we put our stuff in 3 bags so we don’t have to carry more bags and airline also save space time less bags less work. We had only 1.6 kg over and we requested crew he said it’s airline policy that you need separate bag that’s ruined our mod and carry that suit in our hand in plastic bag he didn’t understand that we have less bags that make sense if we brought over luggage then it’s problem. I think if you guys change your policy and weight all together that will be good

Was not good experience going to Houston from Istanbul, had to wait about an hour and a half to just takeoff. Disappointed in that part.

Great service, great food, and comfortable business class seats... Friendly and professional flight attendants and ground crew, overall 5 star experience!

Flight staff and all was fine. Food always sucks on planes so nothing new.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

The staff were polite and professional. I found the boarding for First Class Business customers not great. They didn't offer me pre- boarding. Just regular zone 1 boarding which didn't feel great. On board and throughout all of our United Flights we found the staff wonderful. We'll definitely fly United again.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Great experience. Flight was on time and reached destination on time

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Did not fly to Houston as original flight was cancelled.

Two things to note here. First, Lufthansa separated me from my small children. Apparently you need to pay extra to ensure that your children are not abandoned. This is different from KLM-Air France, where children sit with their parents automatically, and I usually fly KLM-Air France. I didn't realize Lufthansa was different on this score and is willing to leverage the wellbeing of small children to generate more revenue. Second, my flight arrived 3 hours and 54 minutes late, so I am entitled to financial compensation as per EU passenger rights regulation. From other aspects of Lufthansa's behavior during this trip, I expect that their approach to this is to start a war of attrition with their passengers to avoid giving compensation as much as possible - again, very differently from KLM-Air France. But we'll see, maybe I'll be pleasantly surprised.

The plane boarded 5 hours late. This made for a very long travel experience - 3.5 hours for getting to/taking the connecting flight (Air Dolomiti), 5.5 hours layover in Munich, 11.5 hour flight to Houston, 1 hour ride home. After landing at BUSH airport we spent 30 minutes on the tarmac waiting for United staff to prepare the jetway. Flight attendant admonished my wife for briefly opening the window shade midflight to take a look outside.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Late from Istanbul. Canceled my seat to NY in London although I've been on time for boarding. Didn't provide with hotel and shuttle, no food, just sleeping and hygiene bag. Hope, they will refund me.

They cancelled our flight the morning of departure at 4:30am.

The staff were very friendly and helpful. The seat configuration was as awful which meant no one had any privacy. The food was very good.

We flew business class. The staff was polite and responsive. The accommodations were comfortable and spacious. The area was clean.
