Airline reviews

Hainan airline provide direct flight from Boston, US to Beijing, China, which is very convenient. The only issue we had was that my infant bought full ticket, however, when he was transferring from international to national flight (Beijing -> Shanghai), we were informed that the infant didn't even have a ticket. It probably became an issue because he was not allowed to have a seat within China. Hope this issue will not happen again. Otherwise, we like this airline, the services, food, timing are all perfect for a lengthy international trip.

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

The absolute worst experience I’ve ever had flying. I am a regular flyer and was transferring from Seoul to Beijing to the USA. I was told the companies were partnered so no need to pick up my baggage, I got through eventually after a terribly confusing airport and unhelpful staff, had issues with the check in counter where they didn’t understand my baggage tag from the previous airline and that my bag needed transferring (which as a company partnership they should have communication like this) and then I got through extremely stressful security with multiple stops and the plane was poor quality (same exact quality as my 1.5 hour flight there) for a 16 hour flight with poor food quality, slow trash service, and less than 15 movies total for flight options I was absolutely over it. My only good thing was I was lucky enough to be sitting by myself in a row

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.

It took almost 4 hours to collect the luggage from the belt in Lagos. Really pathetic. Flight attendents from Dubai to Lagos were very busy and were not responding at all.

Everything was perfect. Staff were informative and professional and flight boarding, flying and de-embarking was smooth. I would certainly travel with Emirates again.

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

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

We loved flying with Emirates in business class, the staff were fabulous, going above & beyond

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.

Seat 💺 was all the way on last row. Food was okay .

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.

There was no screens on the flight, and no wifi with which we could connect to the internet and stream any content. This was a smaller plan so the business class seats were a bit tight. No hot towels or welcome drinks like when you fly on the bigger TG on the same route. The food was excellent, much better than the previous Thai airways business class meals. It was also nice that they offered eye masks for easy sleeping.

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.

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.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

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

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

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 flight was small and was not cool very bad

Excellent service and great help when i traveled with broken leg

The seat was not functional. Very uncomfortable to sit upright for that many hours😢. There was no legroom. Can’t move the legs or the body. We should have the option to pick our seats. There was no need to call customer support team and have them pick and we pay for the premium seats. When I called the CST regarding the seats, their response is gaslighting. Total disappointment. We have paid to be tortured by Etihad Airlines.
