Qatar does not answer phone calls and communicate with travelers about trip cancellations

The seats have so much room. They give great free snacks. Staff was so nice.

They made me check my bag and I didn't need to as there was overhead space available. I paid for a seat towards the front of the plane and it didn't recline. I requested a refund and they declined to give me one.

Very smooth flight, good legroom with the "even more room" seats. Entertainment choice was excellent, wifi on board, plane was modern. Pilot got a round of applause for a smooth landing in very blustery conditions. Love flying with them. Check in was OK too. We were too early so we had to wait until groundstaff showed up 3hrs before the flight.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

They initially informed us that the flight was delayed, but only after waiting an hour for updates. In any event, the flight was canceled, but the way it was handled was really poor and egregious. I feel they handled the situation of informing travelers very irresponsibly. I sat in a wheelchair at the airport for over four hours before finally being told that the flight was canceled.

Friendly crew, efficient boarding and flight arrived early. Couldn’t ask for a better experience

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.
