The flight went great. Of course sleeping is always a challenge for me when sitting up but there’s nothing they could’ve done about that. All went as great as it could’ve. Food great, friendly flight attendants and good entertainment.

The flight went great. Of course sleeping is always a challenge for me when sitting up but there’s nothing they could’ve done about that. All went as great as it could’ve. Food great, friendly flight attendants and good entertainment.

We flew with Qatar Airlines before (2021) , the service was much better than this time, the flight attendants were not very friendly and cheerful . One of the attendants asked the person setting next to me (by the window) are you Mr. ……, if you may need any thing to let her know . I asked for a dinner meal with beef , she said, we are out, only chicken is available, then she said wait I may get you one with beef, she came back and gave me chicken. Then she gave the gentleman next to me the beef meal . The bathrooms were left dirty and full of overfilled paper tissues, urine every where on the floor and on the toilet seat . Qatar Airways has an excellent reputation and deserves better . Thank you 🙏

Horrible horrible plane for such a long flight. I thought Qatar was a reputable airline. Was proven so wrong. Never again…:-(

Qatar Airways has consistently set a standard in my mind that very few airlines manage to sustain, and once again, this journey in Economy Class lived up to that expectation. As an avid globetrotter who travels extensively for work, I experience many airlines, service cultures, and levels of hospitality. Yet there is something reassuringly consistent about Qatar Airways. It is not simply the onboard service, but the entire experience: the professionalism, courtesy, warmth, attentiveness, and genuine sense of hospitality. The cabin crew are exceptionally well trained, composed, aligned, and polished in their delivery, yet their interactions rarely feel mechanical. They remain remarkably courteous while retaining a genuine human warmth and an apparent eagerness to assist. On almost every Qatar journey, there are individual crew members who somehow manage to stand out and make the experience even more memorable. What I value most is the consistency. Qatar Airways has established a certain benchmark of expectation for me and, over many journeys, has never underdelivered against it. There is a sense of confidence and ease that comes with boarding a Qatar flight because I know the overall experience will be thoughtfully delivered. For someone who spends a considerable amount of time travelling, that peace of mind matters enormously. Qatar Airways remains one of the airlines I genuinely enjoy flying, not because of any single aspect of the service, but because of the complete package and the remarkable consistency with which it is delivered. The only disappointment on this occasion was that my luggage did not arrive with me at my final destination in Kolkata (CCU), following my journey from Seattle (SEA) via Doha (DOH). Unfortunately, the baggage was delayed in Doha. A baggage exception report is already on file with the local airport team in CCU. Given the confidence Qatar Airways has built with me over the years, I remain optimistic that they will once again live up to that expectation, work their magic, and reunite me with my luggage within the next 24 hours. Looking forward to a swift resolution and, notwithstanding this final hiccup, another thoroughly enjoyable Qatar Airways journey.

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

Bag check in at DC was slow. Boarding process was slow more due to customers unfamiliar with how to board properly. Food and service was excellent!

The hindu meal food did not taste good. Also the seats were not comfortable as compare to other airlines

The first and longest leg, Washington to Doha, was in a 777 that was very loud. This was an older aircraft. The second leg, Doha to Delhi, was in a much newer aircraft, an A350 and was very substantially quieter. The service was good on both, though as always, the crew leaves you trapped with your meal tray for a really long time. Additionally, the flight crew seemed inordinately afraid of turbulence, keeping the seat belt sign on for long stretches when there was barely noticeable turbulence.

When getting to our seats a blanket, headphones and pillow where there already. The food was very good and plentiful. I liked when they came around w/hot towels to freshen up with. Slippers, socks and an eye mask was a nice surprise. My husband and I have mobility issues and the transporters were absolutely wonderful and helpful w/the wheelchairs at each stop. Getting from one gate to the next they were a blessing.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

the cabin was kept too hot. couldn't sleep as a result

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

Awful seating. Bad food. Staff only have one bottle of water and no cans.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

They over booked the flight from Abu Dhabi and put me on a flight 2 days later. Unbelievable experience even after booking business

The first segment from Atlanta to Abu Dhabi was fantastic, but we got downgraded to a different aircraft from Abu Dhabi to Delhi. We were supposed to be on a flatbed business class when we booked it but just about one week before travel, we were changed to A321 Neo, which just has old-fashioned business class seats that recline but don’t go flat. While I fully understand that sometimes these changes have to be made for operational reasons, but I asked for some credit or compensation for that and I did not get any anywhere with that

Luggage jandling sucks. I arrived in BLR india on 15th and luggage was delivered today 19th. I came for a business trip everything got screwed up. Poor communication. APP kept saying mishandles in BLR. It never reached BLR. I had air tag which showed luggage was in Germany. I could not reach anybody other than the airpprt people. They had no clue and asked me to call etihad. In India etihad number wasnt working.i had to call US number and that person was the only person who seemed to help. They kept me in dark. No communication or email till i spoke to the person in US.i have flown many airlines but never had this experience. For me this was first and will be last in etihad. Very bad.

Awful , hidden charges for the luggage was a very awful thing, very much a scam , booking the flight thinking the luggage was included was definitely a scam , then the girl that was taking my luggage Ayrlease the airport was an absolute awful , telling me if I don’t have money to take my luggage with me I can just throw it away , how professional, NEVER AGAIN .

Connection booked by Etihad was delayed and upon arrival to counter they closed it and denied boarding although there was still 15 minutes to go . Manager Karen was very rude and did not want to listen seems there as overbooking and canceling boarding was the only solution..

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 !

I had a terrible experience checking in at the airport for my flight. I booked my ticket initially through Kayak while it was promoted as a ticket that offers a carry on and 2 suit cases. (I have a screen shot as a proof of it) I selected it to buy three tickets and paid online. Couple of minutes later airfare assist which is the OTA offering the ticket called me saying My card declined. So I used a different card that went through. I was surprised that they increased the price ticket by a $167. They said the ticket no longer exists and because my card declined I had to buy a new one. So I did. The day my family and I were traveling I could not check in and when I went to the airport I was shocked to be told my ticket had no bags allowed and must pay $200 per bag for three people 6 bags mean I have to pay $1200. I called the travel agency as I feel I was scammed the confirmation didn’t say anything about the bags and they never told me the new ticket doesn’t not include any bag so they changed it after I selected it on your app without informing me. Very sneaky. The travel agency said they will reimburse me only for one bag person. Which means I still paid $600 I still feel very disappointed to pay such an expense. I have always used Kayak to buy my flight tickets and telling everyone how good your rates and app are however after this I feel I was mislead and paid more for something I should not have to. You allowing such an agency on your platform will surely hurt your reputation and level of integrity. I have all the proofs from the screen shot to the confirmation email from them, the or email offering to reimburse o e bag per person and the $1200 bag fees receipts that I paid on the desk. I must be refund the full amount and I look forward to your response.

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

Short. Nice quick flight, appreciated after Munich to DC leg.

The flight from Frankfurt to Pisa was cancelled and we were rebooked to route through London. The flight to London was delayed for maintenance issues and we missed our connection flight. Lufthansa automatically rebooked my wife on the next flight but I was not rebooked. I spent over an hour trying to get onto the flight. Ultimately my wife’s gate checked bag from Washington did not arrive in Pisa and remained in London. Very bad experience overall.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

Flight attendant incredibly rude. Stuck her finger in my drink and didn’t even have the courtesy to apologize.

The very best airline service I have experienced. Better than domestic airlines first class and I flew Economy Plus!

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight was on time and smooth. Customer service was decent

They forced me to check my hand luggage at the gate.

Still hasn’t left. Why are you asking how it was?

My flight got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.
