Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

You are the best, keep up the good work. Thank you for allowing me and my family to fly with comfort.i am waiting for upgrade some day. Thanks again

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

Plane was good Crew was good Food was just ok Could have had more entertainment options But overall good

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

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

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

Indigo airlines is terrible. Staff is awful and so disorganized. They are so rude and unhelpful. I will never travel on Indigo airlines again!!!!!

The staff was the best I have experienced as a frequent traveller in a long time.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Gate agents were late…flight was late and air attendants unhelpful.

Awful it always is unfortunately is the only way to fly direct to london

The flight went well. However the leg room in coach class is very very tight. We arrived early but could not get to the gate early….sadly. Also something about off loading cargo- we had to wait to deplane. There was not clear explanation for that.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

Ohooo it's fantastic 👏 I love it 😀 😍 ❤️ it's on time ⏲️

Need thicker and wider blankets. Food was below standard especially in the fist leg.

I travelled in business class and was disappointed by lack of service, curt and borderline rude time of the crew and to top it off, all of my luggage was delayed. It was like pulling teeth to even report the missing luggage and recover it the next day from the airport.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.
