Terrible plane small airbus good for a 1 hr trip I booked business as it is. A night flight and 4hrs trip it was an ordinary economy seat with no one next to me what a joke what a stupid decision to buy business

Seats are too cramped, but that is a problem with every airline. I actually enjoyed the meal served.

Crammed like sardines into the middle of the middle 4 seat row for an 11 hour flight was a terrible experience. No attempt made to help passengers sleep by dimming lights or shutting window shades. Small mediocre meals. Not enough good movies/TV options. Hopefully we will never have to do this again.

better announcing at the gate prior to boarding and better organization of various gps

Flight attendant served beverage to everyone during meal service and forgot about me. Had to call her several times until she realized it. Not a good service for a business class flight

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

Ghe issue was with the delay caused by the late boarding. We had to run to catch our next flight, barely made it and then our luggage didn t arrive with us. Really bad organizing.

This was an upgrade to business class and really enjoyed the experience. Much better than my earlier flight and thank you.

Flight was very full and we had to checkin our carry on. Stuff however promised us that our luggage will be the first one to come out and it did

Stuff was very helpful at checkin. Flight attendants were nice. Food wasn’t very good, I expected a little more. Economy Seats are ok. Second flight was very full and they forced us to checkin our carry on.

Check in was not available online. It was super long line to check in

I did not have a good experience from the first point of contact to the check in person to boarding and the comfort of the seats. I would not travel on Turkish again. I will let my family and friends know about my experience which was not a pleasant one.

They sell the option to select chairs in extrafly price level, but this is not true. I was not able to select the seats. The food was not the requested option. They suppously offer glutten free menu, but during the fly that was nos availble.

Did not expect no entetainment, food was ok. No alcohol on a. International flight

Very poor! It was too hot! It smelled. The food was nasty. The bathroom sink to wash hand was barely working. The tray table was broken. Everything was just wrong!

The internet was not working during the 10 hour. This situation was known by the cabin crew before the flight. If so, information should be given to passangers. Some people should work during the flight.

Seemed like a cramped A321 config. Roasting hot cabin most of the flight. Wifi did not work. Lots of first time fliers, I think, who didn't know how to follow a seat assignment.

My checked bag did not get loaded on the aircraft in Istanbul. Other than that, the flight was smooth, on time and the crew was friendly, efficient, and professional.

Unfortunately internet was down and they couldn’t fix it in a time I needed it so urgent to stay in touch with work

Everything was great except the meat served was tough and overcooked!

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

Only 1 time food and drinks together was offered, for total 5 hours duration drinks and snacks was never offered. For some people food choice was not available, only veg was available. No entertainment option was there. Crew members were mostly back of the flight asking each other for KitKat and chips to share between them.

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 time with. Etihad Airways and it was amazing from check in to crew. Great flight.

Boarding was unorganised. The flight was very uncomfortable, the temperature was far too high. On requests to lower it nothing changed.

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

The flight crew, the on-plane service, and the food were fine. The seats lacked cushioning and were uncomfortable compared to other planes from recent flights. The plane was initially delayed one hour and that expanded to 1.5 hours. When we boarded, there was insufficient room for our carry-on bags, which added more time to disembarking from the plane. It appeared the Air Canada staff or the Toronto Airport staff were less than competent to handle whatever the issue was that caused the delays, which was never communicated.

Boarding was haphazard after people with small children or walking difficulties

The smell of vomit from the previous flight was overwhelming for a 9 hour flight. There must be a chemical or product to kill the smell before the next flight boards??!!!

Boarding process was hectic and unorganized. Delayed for hours, THEN delayed for weather.

Due to flights being delayed, we missed our connecting flights and we were flown to a different airlines and we end up losing our luggage's.

The boarding process is not well organized at all. It need to be totally revised with an emphasis on order.

What food? What entertainment? The questionnaire does not make sense.

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

3 hr delay. No water given while on the plane for 3hrs.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

I am 70 with carry on bag. Was told to go down two flights of stairs the had to climb stairs at rear of plane. Skywalk to front of plane was not offered. I was in row 26

The seat was a bit crowded since the person in front was reclined. It’s my personal belief that if the seats are allowed to recline, there should be more room. The service provided by the crew was the best I have experienced.

Flight OK but they only loaded half of the checked bags on. This they only told us on arrival

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.
