Food could of been a bit more premium, but everything was excellent. LOVED the innovative boarding drinks and terrific service!

Staff could have been friendlier and offered drinks more often

Staff friendly. Business class but issue with flat bed. Incoming Turkish flight delayed. Made connection due to fast buggy but luggage did not make it. Confusion at Delhi airport

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

Very good overall.... apart from the cost of extra check ed in luggage where they charge £17 per kg, and no option to just buy an extra bag allowance (at least on the route I took)

Seat changes at the last minute Horrible checkin process Sad to see excellent airport with very poor service

Very old plane on the Istanbul to Bangkok flight, had an emergency exit isle row, no where to put anything, on a plus point loads of leg room. Food was the best I have had in 39 years of flying.

Don’t use them on the IST-isb route, horrible service

A good airline, but at checking in, they allocated seats for my wife, and I far away from each other, and to change them, they wanted a payment, such a bad policy, it leaves a bitter taste in the mouth All was good on the plane, good food, but the air hostess was abrupt and a bit rough dealing with the passengers, but one has to find excuses for staff working under pressure

I found it okay. Did not think the food was that great. And the service could have been better. Seat was a little cramped. Delay getting to Istanbul made me rush all the way across the airport to get to the connection. This was a not good experience.

I have paid extra money for my special meal service but I received the the local food. Which is not acceptable.

More entertainment channels and better food, whatever food requirement you select.

The flight from NY to Bangalore was very good but the return flight from Bahrain to NY was mediocre

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

Worst flight ever.service was extremely poor and food taste was horrible.Served me mashed potatoes and chicken calling it Briyani.

Had to discuss more than 15 min regarding wheelchair they gave only at the start location. No food serv in 1 st flight. Considering flight started at 10:00 pm so had to starve for dinner. Checkin screw was polite. Food in 2 nd and 3 rd flights was not good. It was too cold in the flights. Had to ask for blankets. Missed quality all thru, though the fare was on higher side

I like it very much. Gulf Air is always the topper rank of the world. I love it very much.

The drinks should come before food. Unable to have any fluid unless after food. Thanks

The entertainment on board was really poor. The map doesn’t give enough information and the movies have arabic subtitles, you can’t choose. The stuff wasn’t very friendly and the breakfast really poor. The food must not be spicy! They didn’t have enough drinks.

The boarding at Heathrow is chaotic. That's partly due to the lack of space and seating at gate 8, and a Qatar flight from gate 9 at the same time. That's down to Heathrow rather than Gulf Air. I've had a similar experience here before. Another problem which isn't specific to Gulf Air or Heathrow is announcements, and those for boarding in particular. They are difficult to hear with all the other noise and for me with hearing problems it's even worse. A simple tv screen would help, so long as it's updated of course.
