One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

My flight going to doha had economy seats that had a little more leg room. Coming back the leg room was not there. I'm 6'3" and my knees were against the chair in front of me. I couldn't slide my feet under the chair. The 15 hour flight felt like torture from the lack of sleep I was getting being so uncomfortable. Food and crew were great though.

It was excellent except for at the very end. I woke up about 1.5 hrs before touchdown and wanted to order food in the Business class. I was told they had shut down food service. It would have been good to get a heads up before they closed the service. Anna the air hostess was wonderful. She did get me 2 bowls of fruit and I was very appreciative of her. Wonderful human and a hostess.

Amazing airline accommodations. The cabins were so great. The food was very good and the flight attendants were so nice. Made a 15 hour flight seem easy.

I paid extra for seating when first booking flight to be in a comfortable economy seat They still changed it to a middle seat regardless. When I asked for it to be changed back to aisle, they could only give me one at the back of the plane in the least comfortable seats.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

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.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Vistara i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience Qatar Delhi .. only complain .. no clear signage to lounge for transferring pax .. its a Delhi shot coming.. no feeling of exclusivity for biz/ 1st class pax.. but everything else was much better .. once i boarded Qatar .. i loved it Qatar to Washington .. only complain i boarding .. too crowded .. no separate area for biz/1st class should hav completely separate area for upper class.. security is stifling pax comfort by the gate ..but everything else was great

Good could be better. Crew is good but not great. Not much snack options for kids. Bathrooms were not cleaned on time

The crew were really bad mannered! And spoiled all my mood throughout the flight!

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

It was excellent service in the snow storm gives us hotel and transportation. It will be more better if u can add one more meal because it’s a long flight boring journey. If you give extra meal time passes faster and can enjoy the trip better

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

The crew could have been more friendly and could have offered to make the beds. Also, Ethiad should have more vegetarian food options.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.
