Do not fly - upon customer service if anything goes wrong.
The airline's app won’t let you access if you’re not in China. They don’t answer the phone on their 24/7 helpline. The carrier they used for one leg of our trip (KLM) changed the time of a flight & China Eastern rebooked our tickets but didn’t confirm, so KLM wouldn’t book us through to our home destination, they wouldn’t answer the phone and so we got stuck in Amsterdam. These were business class tickets, so can’t imagine how they treat economy passengers. Ended up having to buy new flights to get home and no responsibility taken by the airline. We now have flight centre chasing them for our refund and they keep hanging up on them. In terms of service, we were unsure why the flight attendants seemed annoyed with us, hard to get a drink of water in business class, but having now flown Emirates economy home, I don’t think we were the problem. Would never fly with them again.
