Best domestic flight I’ve been on for a very long time. Way better than any of the Australian carriers for domestic flights!!

The seats and service exceeded expectation for the price I paid for.

My first time flying Hainan Airlines. Boarding process was easy and quick. Staff was friendly and helpful. Food was a simple, hot meal which we don’t see much any more on short flights in the US. Only water, coffee or tea to drink but it was only a two hour flight. Overall pleasing experience.

Great although I believe they are able to redistuibute the passangers in a more comfortable way if the flight is not full dor such long flights. Unless the seats are paid for, of coruse.

Good flight, on time. The aircraft was old and the seats lost their shapes. Food was just acceptable.

Two hours delayed departure ! Lost one of our luggage! Two days later found the luggage, again waiting for more than two hours to get the lost luggage because locked at other airline office.

Hainan Airlines was amongst the best. It's sad to see her becoming just mediocre. I recommended her as outstanding. I won't recommend her again.

Such amazing service! Wonderful flight attendants who actually care about the passengers and go out of their way to make our journey easier!!

They asked how much cash i have . I said no cash they said bring cash from atm . Why they even care about my cash.

Flight was scheduled to depart at 1210 hrs. It was delayed 1 hour 20 minutes (maybe for air traffic control reasons). The seats were worn out and very uncomfortable. Lunch was typical for airline. Flight free were friendly.

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

One of the female staff from the cabin crew, forgot to ask us about what we want to drink and focused more on other specific people rather than treating everyone politely. I asked her about the drinks to which she said oh I forgot.

Very uncomfortable aircraft. No free entertainment or drinks. Food okay. Won't fly with them again.

Comfort poor, little leg room, cabin temperature too hot. No free entertainment. No complementary drinks. Overal experience poor and would not travel with them again.

The plane was clean and well maintained the crew members were professionals and friendly and the food was good

Worst trip ever from the beginning to the end I will never travel with that airline again. I made a big mistake by not going with my regular schedule flight with Qatar airline. Even underpriced cheat me of my 134 dollars I paid for special seats and they kept my money and didn't pay the airline for the seats for me.

Food was good, great communication by Pilot and Co Pilot, Crew very friendly. Slow beginning drink and meal service - over 2hrs into flight which disrupted overnight flight sleep. Entertainment systems was 3 Stars, my wife's was nonfunctional and had to call attendant 3 times to get it reset, mine the headphones and jack we're twitchy and keep going to muted volume.

Everything was good but I think food choices could've been better

Boarding took forever! Was disappointed at checkin that they did not let me pay for an upgrade for my mother who has bad legs ! There was a seat available but they kept saying you need points ! I think that’s total BS! I had the money to pay and they made it so so difficult! Mean while onboard there’s a video showing pay upgrades available!!!!! The exit row seats we are were ok but super narrow ! Staff is wonderful

It was also a great experience except to the inconvenience of connecting flights since we need to took buses to go to another terminal and the boarding was easy but if you manage to find the terminal in time. Still it was a great experience with Kayak and Emirates.

Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

USB charging port was not working at my seat 48K.

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

Service on board was excellent. Flight attendant was very helpful. I wish the website is more functional. I can't even choose seats online and had to call the customer service. During check-in at the counter in CGK, I saw a printed page about paying for the bulkhead and exit row seats, so I asked the staff at the check-in counter. I was told that the flight is full and there isn't any seats available for paid upgrade. When I boarded the plane, I saw so many bulkhead and exit row seats empty and asked the flight attendant. He allowed me to purchase the upgrades on board. It would have been nice if I could purchase the upgrades ahead of time, eg. During online check-in or bag drop at the airport. The economy seats in the A350-900 are arranged in 3-3-3 configuration. Seat width is a bit tight for me.

The flight was over 1 hour late taking off ,when I arrived in Abu Dhabi ,I missed my connecting flight to Bangkok so I had to wait almost 6 hours for my flight arriving in Bangkok at 6:30 am ,So I missed a whole day of my vacation and my hotel room sat empty so I paid for hotel days that I was not there. In Abu Dhabi there was a woman that worked the desk at transfers that was so professional, courteous , helpful,and may I say absolutely beautiful .she got me food vouchers for my layover and was a very calming presence. Besides that I will never use Etihad again I will pay the Xtra money . I'm sure they won't read or see this but it's my "2 cents" I'll use an airline that respects me and my hard earned dollars

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Same problem place in the middle so small Im 1,85 m so not good 👍

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

A380 First Class Apartments were phenomenal. Comfortable bed and matress cover, superior vegetarian five course meal, shower, small business lounge and plenty of exercise walking around the aircraft.

Took a long time for boarding. The flight was comfortable.

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.

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

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though
