The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

The flight overall was good. The attendants did a good job except that 1 female had too much fragrance on. The other things that made the flight unpleasant were out of the airlines control.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

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

The flight from Gilgit to Islamabad was cancelled. I had to arrange alternate transportation to Islamabad that took over 12 hours drive over a dangerous mountain pass with mudslides that were still being cleared as we drove. Could I please be given a refund for this cancelled flight?

Poor also they kelt changing dates of ticket! Not recommended

I am very certain that the food on this flight caused food poisoning.

Overall, it its good , needs to improve the food quality and more variety of food

Flight was good but it started half an hour late

Food was 👍 great , seats are a bit narrow, crew is helpful..

The flight was canceled two times and didn’t tell me on time I was waiting all day long for my flight but at the end it was worst.

Flight was good and on time. Check in long time could have been avoided by having more counters at the airport
