Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

The airport crew helped a lot, what I didn’t like? We were not informed that we needed to pick our luggage’s, if the crew at the luggage center didn’t tell me I would have been home without my belongings, I was heading out to my next connecting flight while looking for what gate to go to, I asked one of the crews for help, he told me and he also told me to not forget to grab my luggage’s which was chocking, because on my way out the country that wasn’t required, I just hope none of your customers lost their luggage’s because of this.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

The flight crew was friendly. I tried to adjust my seat online ahead of time but no option existed without additional fees. My friend asked at the gate about a seat change and was able to make it happen. That was great! The flight crew moved a very tall gentleman and his companion which allowed us to have more space which was nice. Overall, good experience. Appreciated the blanket and pillow.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

Amazing trip! No delays, no broken or lost luggage, and amazing food.

The food we received during the flight was excellent. The service was very friendly. Definitely the best value for the money when flying across the Atlantic.

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.

The security at the airport was excellent. The one criticism is the boarding process just before entering the plane. There were only 2 boarding lines and there were no barriers thus leading to a mass rush to enter the plane. I suggest that they board by rows, eight or ten rows at a time to prevent the mass rush to enter the plane. Otherwise, I would highly recommend Turkish Airlines

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

I paid for full WIFI- it was terrible, kept being in and out could not listen to a podcast

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.
