Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

Our male flight attendant was top notch - wish I could remember his name. Boarding is never fun when I have to ride the shuttle to the middle of the tarmac and pull my carry on bags up the stairs to my seat. My knees are banged up and my shoulders give me pain, so the flight started off poorly. The seat leg rests don’t recline completely so that makes is difficult if not dangerous to get in and out of the middle seats. The entertainment system touch screens prevented one from seeing the options. They are old and the software needs to be updated. I was on six planes in the last two weeks and able to see the flight progress without any stress. Couldn’t watch anything else. I do like Qatar Airways, just not a fan of a few things.

Was downgraded from business to economy due to a faulty seat in business class. However when I boarded the plane there were no less than 5 free business class seats. Will never fly Qatar Airways again

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Moved seats, didn't accommodate requests to change seats even though other seats were available.

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

Do I need to repeat my complaints about my lost carry on bag?

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

In never flown this flight, because my flight coning from Barcelona was delayed.

Etihad flight sector is a local . .give the same quality upto destination

Long way to improve. Toilets not working. Bad handling when flight was canceled

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

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.
