Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

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

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar, wake up and do it right by your customers, or they may not be your customers anymore.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

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

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

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.

Mumbai airport is a nightmare! Especially going from domestic to international terminal (2). I almost missed my flight. Then i could not check in because I purchased on kayak to British airways and my first flight was an indigo (non partner). So they called me when I was at the security outside the terminal and told me I had a middle seat, not what I paid for! After talking to the desk agent, they could not help but it finally worked out. A bit stressful for no reason. Probably never buy from kayak again this type pf complicated tickets (multi cities).

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.

Crew was good. Seat was worn but overall okay. The infotainment system is outdated and needs to be updated. BA should provide free WiFi for club world/business class passengers.

I really liked it when the First Officer mentioned that we could see Paris out of the window on the left.

Pilot announcements were clear. Boarding is too slow compared to budget carriers.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even
