we bought trip insurance from you and could not use it. 'underrated' only return 50 % of trip cost. my doctor told me i have stage 4 cancer and that I might not live till the end of the month..

I liked everything accept the delay try to improve in that area

The customer service was very poor. I didn’t get any accommodations for my cancelled flight. I was without any sleep for 36 hours.

On the Dubai-Gatwick flight the only meal options were Beef or Chicken. No vegetarian option. This was a surprise. I would usually order in advance but did not this time. Would have been good to know that a vegetarian meal is not available as a standard meal. Thankfully it was just me travelling, but if I’d had my kids with me that would have been a big problem for us.

My Experience was ok. But the gentleman next to me vaped the whole flight and the attendants did nothing, whether they were aware, I’m not sure.

The crew manager let the staff down by not ensuring special dietary requirements meal were coming in drips . The poor cabin crew did not stop . If organised the cabin could take a short break ..The cabin crew were AWESOME UNLIKE THIER TWO MANAGES!

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

The lounge Emirates uses at Jeddah airport is horrible even with the opening of the new section. Food selection is poor and never enough seating . Staff are not friendly. Boarding process at Jeddah always an absolute mess

Check-in counter at the airport took more than an hour of standing in queue with online checkin. And after entering the gate the flight delayed more than 30 mins.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

The made us waiting and held our passports and boarding pass making us miss our flights

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

To many ads. 3 or 4 between each movie. All repetitive, all related to Doha which I was just passing thru.

My seat that I booked over a year ago and some other passenger was sitting in it. They said they could not walk and they would not move. I was with my young kid and the crew did nothing to accommodate that. Just disappointed that the airline accepts that excuse from a passenger.

They shld improve and provide a lunch or dinner in an international leg

Terrible. The website insisted that I wasn't logging in correctly to confirm my flight. It also wouldn't let me register as a member. I was unable to get a boarding pass until 4 hours before the flight so I couldn't get through security and had to wait. It was unlike anything I've experienced in decades.

Very very poor service. Authorities must take action against this airline immediately. Total failure to follow the rules and regulations of an international airline

There was not enough staff during boarding which had created big problems . Another thing once you enter gate area there’s no way to use bathroom and you have to be in that area 2 hours before boarding which is too much.

I encountered challenges with the boarding staff during the boarding pass issuance process, leading to disagreements. Despite my agent's information that carrying a small cabin bag along with a separate bag containing my laptop and purse was permitted, the boarding staff did not allow it.

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.

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

In my opinion, Etihad Airways is a first rate airline except for one important element. On the day before my return flights, when I chose my seats on the Etihad website I was charged an additional $55 (US) in order to sit on the aisle. I was not at all happy about this additional "hidden" charge and I felt cheated.

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

Crew member took too long time to take back leftover food plates from passenger seats. Food was nice.Easy excellent checking.Guy at checking counter was really kind and helpful.Made our checking very quickly. Leftover food should be taken back ASAP. Because in economy class passanger have narrow space . In the long journey like this, passanger have difficulties to sit with the plates.overall experience was good.

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Very very bad service very tight seats never ever flying with Etihad again

Check in was quick and gentleman was very nice and friendly, during flight crew members were polite and attentive, food wasn’t as it should’ve been. Entertainment section needed to be updated i.e add new movies

Entertaiment center needed on that flight. I dont like to use my phone for entertainment.

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Very professional and well managed. On time, great staff and comfortable.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

I m not good serves poor serves I m m fake company kayak ok plzz my help my ticket cancel my tripe ok

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Aircraft used fir this route was pretty old. Seats 💺 were hard & difficult to reclaim although it was flat bed

Because of the bubble agreement b/w India and Srilanka, I was not allowed to board the flight to Columbo. My experience about airport representatives was good. They were through in their job and saved my family from getting stuck in Columbo (as I would not be able to fly to Doha because of bubble agreement). So by their prompt attention, such a catastrophe was avoided. For this reason, even without flying with them, I would rate them 7/10.

There's no inflight entertainment, plane was old, power USB didn't work

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

Excellent. Very nice and comfortable business class. Only negative is that it was difficult to hear the pilot’s announcement.

Food not so good. Need more veggies and whole grain especially the late food. Couldn’t figure out how to use the entertainment system.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

The first class flight itself was first class, however getting to the airport and getting through the airport was agony. The BA flight sat on the taxiway for ages and caused us to miss our connecting flight which meant half a day lost. Our return flight on BA was cancelled so a dawn flight was made and we lost another half day. Goodby BA

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

There was some delay at Heathrow where a machine needed to "start the engines" wasn't available and they couldn't even find the team tasked to do it. Unacceptable. Caused about an hour delay and seemed unnecessary. Also saw several passengers abusing the overhead luggage situation, having too many large bags and not leaving enough space for others. The crew was good and the refreshments were good in quality and quantity.
