OK 5.0

Pros: Food

Cons: No entrance forms for foreigners to fill before landing. Shocking to learn that A black guy found "dead" in the middle of the flight, probably due to heart attack China Eastern web site is horrible as it only allows passengers who bought their tickets DIRECTLY from their web site to access booking managing like seat choice and printing boarding pass. If you bought tickets from travel agents like Justfly.com, forget to use China Eastern web site to manage your booking, HORRIBLE, HORRIBLE, HORRIBLE

JFK
PVG
Excellent 10.0

Pros: The actual flight was really fantastic, food was warm, flight was relatively comfortable/smooth, entertainment at least for me was good, since they had a decent amount of Japanese music to choose from, and the attendants were friendly and nice. Everything was 100% on time as well. I could complain more about tiny tiny things, but for $500 I felt I got a lot better service than United on an equivalent route.

Cons: Seats were slightly stiff, but not too bad. Only bigger issue was upon boarding all the people lined up in a 100+ yard line and caused a bit of commotion instead of waiting for their seat numbers to be called and forming a small normal line. This is in no way the airline's fault, and they tried to make it work in spite of the people doing it, but as a Westerner this was confusing.

Cons: Check in crew was so inflexible, and demanding. She wanted me to open a careful-sealed box just to take a pound out. Whrist my other luggage was only 48 pounds! I understand it is part of my fault not to be careful when weigh the boxes but she should have asked nicely. I would rate 0 for the bad behavior. This is not a first time I have bad experienced with United Airlines. I would not recomend this airlines.

Pros: The arrival gate was extemely close to the departing gate. I did not have to walk the usually long and exhausting distance from one terminal to another. Thank goodness.

Cons: Broarding was well organized by groups andmoved quickly. The choice of dinner was not an option. By the time the stewardess reached me, only pasta was left. But having italian gelato for dessert was an acceptable compensation. Breakfast ,however, was ho..hummm without any redeeming compensation. choice of beverages was refreshing.

Cons: On both segments of the trip American changed my seat which I. I’d not realize until boarding. Way to late to protest. You pay for preferred seating but then get bumped to a lousy seat with no explanation. Likely because I was a single traveler and an American employee wanted my seat. Better not happen on the return flight

Prices are per person, are for e–tickets and include all taxes & fees in AUD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
