We flew business class and it was impressive. So comfortable with delicious food and very attentive and polite staff. Will definitely fly Turkish airlines again.

To get to jet blue at JFK from any connecting flight you have to go through security again.

Amazing! One of the best kept secrets in air travel!

Could have been better. Bag rechecking could have been eliminated. Gate location and direction need to be clearly stated.

I flew Business with my daughter and son. The service, friendliness of the staff and the comfort of the fully flat beds were phenomenal. Would definitely fly Turkish again soon.

Very comfortable in business class. Excellent service. Good food. Smooth trip.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

My experience with Turkish airlines has been pretty good. I connected from Istanbul to Tirana Albania. One of my luggage’s didn’t come. Very disappointed with that, we had our year old grandson with us! Babiest things were in that bag . Hopefully I get the bag tomorrow or next day !

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 cabin crew was excellent. They were fully staffed and very helpful. The food on the fight was quite good for surpassing my expectations of “airline food“

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Ultimate customer care humble and excellent service oriented crew , perfect timing maintained by the crew . My profound appreciation.

Only negative was dostancevto transfer in Doha with no big golf carts to help us. Walked over 2 miles.

My Tv don’t work the whole from Doha to New Delhi. Overnight didn’t work from Bos to Doha and had to eat food without light

Everything from start to end was good and easy plus clean i enjoy my trip in qatar airline

No boarding passes given at start point Too much wait for boarding passes

Flight delayed, rerouted, communication extremely poor. Crew efficient but robotic, not supportive

Doubled charged me for luggage and lost $520, dug much into my travel budget.

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Good one but just notice that you have to ask several time to get water or coffee .

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

The flight kept getting delayed, but the ground crew did not communicate well to the passengers in the terminal. First, we were told that it was an engine issue. That was understandable. We asked, after the third delay, if it would be canceled; they reassured us that that would not happen because a new plane was on its way from Washington DC. Four hours later, that is exactly what happened. No announcement was made only people who had the JetBlue app learned of the cancellation. They rebooked us on a flight that would get into our destination 36 hours after our original time I had to spend an exorbitant amount of money to book an additional flight with a different airline, the following morning in order to make it to my conference in time. Not to mention the fact that by the time I discovered the cancellation on the departures board, it was too late for me to receive a refund on my lodging in the destination city for that night. Because I had booked with KAYAK, I did not receive any JetBlue email with rebooking information. This is what the information information desk kept telling everyone who inquired about a rebooking. This was my first time flying with JetBlue. Needless to say, after extremely poor communication andover $1000 of additional expense later, I will not be flying with them again.

We were several hours delayed due to confusion during boarding. Evidently the crew could not match the manifest with the boarded customers. After significant time trying to find individuals on board, a crew member walked through the entire plane re-scanning each of our boarding passes. Then we had to wait for a new slot to depart, and when we landed, our gate was not ready. It was a complete goat rodeo from start to finish.

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

Flight left 2 hours late with no explanation as to the delay

I like everything. Blythe at DCA is the absolute best!

Whole experience was poor. Delayed 2 hours. Lied about the delays. Was all jet blues fault and tried to blame on air traffic control. Sent out other let trips and wouldn't allow people to switch aircraft.

My bag was not loaded on my flight. it was not communicated to me until i was waiting for my bag at my destination. there was no confirmation of when my bag was arriving and no way to track it.

The gate attendant in Boston had a high raspy voice and spoke much too fast to be understood. Not pleasant.
