Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

Boarding and deviating was mediocre. At boarding they have not prioritized Business class. During debarking they prioritized premium economy. Also bus rides both times.

I thought I already provided this feedback. 12 hours with no wifi is unacceptable. Lay flat is nice but a bit cramped.

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

2 hours delay, time changes started already 2 days before the flight

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

I am a bit upset with the check in counter, I signed up a wheelchair for my mom so they wouldn’t grant us her boarding pass. We got to the airport a couple of hours earlier and they had us wait and no one ever gave us her boarding pass or the wheelchair, I had to go back and complain when it was already time for our flight to board. Since we got their earlier, I could have easily pushed my mom myself and we could have relaxed and went to the lounge while waiting… when I finally got someone to help us he couldn’t explain how and why they dismissed us in the first place.

I had sometimes my trips with Vietnam Airlines and I like it 😊

Vietnam airlines is just one step upper to the cheapest one (vietjet, if you wanted delays and cancel or feel like a criminal then vietjet is for you) for sure better customer cares and on time.

Seats not comfortable. We had requested vegan meal and it wasn’t given.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

Not good - chair back could not move back for premium economy. Not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

UA is ok. But check in was a very bad experience

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

Qatar was pretty OK for their services but Arangrant was awful at theirs and frankly lied to me. Qatar offers four business class fares and only three of them allow lounge access. This is a horrible policy when you pay so much for business class and shame on them for denying the simple use of their lounges for this confusion. When I requested my business class ticket with Arangrant I knew this and specifically told them I would only purchase the lowest class business seat that would still permit me lounge access on all legs of my trip. They lied to me and said I did and then I was refused this service on my return flights. I had no less than 4-8 schedule changes and got screwed by a late departure from DCA on my double connection to JNB. I lost nearly a full day on my outbound and then had little to no use of the lounges on my outbound flights. To then be denied access on my return flights made the 27 hour trip home pretty awful. Kayak should no longer work with Arangrant as they are dishonest and liars. Qatar should price all four of their business class fares to include lounge access and stop the insanity they have forced on people. My return trip home nearly ruined my entire trip to South Africa and I blame Arangrant for telling me lies and for Qatar for offering insane rules and regulations on such expensive business class fares. For the money I paid to Qatar, I did not receive the full services I was promised. I will probably never use Arangrant and their ignorant services ever again. I will question whether I ever fly on Qatar Airways again as well. When you pay so much and get such little in return, it leaves a bad taste in your mouth. Arangrant gives the whole industry a bad name and Qatar is not far behind them. I can honestly say that the wretched service and way I was treated by both have soured me on travel companies and airlines. It is bad enough that we have an idiot, felon, racist and bigoted president and administration to contend with while he has started an illegal war, I did not expect to get screwed over by Arangrant and Qatar as well. Shame on all of you.

All great, because I was given a seat with extra legroom on this part of my trip.

Qatar maybe considered one of the best ailines in the world but nowadays it is much of a muchness with the rest

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

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

need to improve management and air hostess services. Rest of it’s OK.

some sections of airport are too cramped. The screening of luggage was twice and a huge hassle. They kept saying my boarding the for my next flight was in 10 minutes but were dragging the screening too long. having a 2 hour connecting time with this much delays in screenings is not good. They could see I was traveling with special needs kid yet I was" randomly chosen" to be personally screened again.

Crew members service are at its best Seating area is very compact, could be better

I planned to fly Qatar airways because I have flown them in the past and viewed the airline as a premium service provided. They still price this way but I found the experience to be subpar in several ways. 1 - check in - the line for check in was the longest I have ever had to stand it. Qatar airways does not have enough check in desks at the airport for the size of the flights they operate. 2- Carry on policy - there was little to no notification of changes to their carry on policy. Backpacks are considered a carry on rather than a personal item so if you have a backpack or larger handbag plus a roller size carry on, you were forced to check an extra bag or pay an additional carry on fee. This is not standard practice on other airlines and frustrating given that this was an international flight. On flight experience was good, generally comfortable seats, friendly staff and good meal service.

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

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.

Excellent experience however older aeroplanes used by China Eastern Airlines.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

For the price we paid, we had a really good flight. The seats and bed (business class) was extremely comfortable. I have no complaints. The crew were very attentive and helpful. They spoke English and there were no misunderstanding although their English wasn’t perfect or fluent. You will never go hungry as there was ample food and drinks but their food for mediocre. The entertainment was limited to older movies and the wifi didn’t allow you to access some Social media. Apart from the above, it was a very pleasant flight. Would highly recommend them.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

A lot of value considering the cheap ticket prices. All meals served were Chinese food. Would fly them again considering the ticket was half the price of any others
