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.

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.

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.
