Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak uses scammer sites to steal money from their victims.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

This was my first time ever flying China Eatern and it will not be my last. I was very satisfied with my whole experience and trip. Thank you very much and until soon.

It was just fine. The sirlines did live up fully to my expectation.

The flight was delayed. The staff made us wait in the room that is too small and it was crowded and with no seats available for waiting. They did not tell us why the delay occurred.

While boarding at PVG, there was a ticket checking at the gate, then there was another ticket checking at the bottom of the escalator, which created quite a dangerous congestion. Not sure which idiot made this absolutely unnecessary arrangement.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Plane was good. But food was bad and air host was so rude. I will never fly with China Eastern again

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.
