Impressive as always. It is the airline of my choice, The dessert on the 2nd flight DOH-IAH was somewhat dry (the cake with cream etc) Check-in and boarding experience was fantastic, with the exception of CCU airport where chk-in staff refused to help with aisle seats stating the flight was full and accommodations were beyond him. Once I boarded there were plenty of available aisles. I was disappointed that this could not be done by self during online chk-in nor at the airport. Nothing more to add. Overall a good experience, TY QTR

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

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

It was little disheartening and disappointing. Although flight staff did a good job. But customer service didn’t do anything to resolve my issue.

Seated in row 6 you are separated from business class close to the toilets. The is a high panel in front that obscures forward viewing, coupled with no window view. Service is limited as the area is not in view of the attendants. It is closer in proximity to economy than business class.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

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!!!!!
