Quick flight, comfortable seats. Leg room is superior than most economy flights. Was surprised and pleased that the domestic flight had English announcements and they were clear.

Announcement at gate to board bus was not delivered, had to look up and see passengers boarding bus to take to tarmac for boarding. Bus then stopped at plane for 10 minutes seemingly waiting for 1st class bus to arrive and board first as they came and were unloaded right away.

There was a long line for the Hanoi-Ho Chi Minh flights but with multiple counters devoted to this route alone we were checking in not long after having been dropped off at the airport. We were offered seats on an earlier fight which we eagerly accepted. Knowing that this route is often cited as one of the busiest in the world it was no surprise to find ourselves on a wide-body jet, Airbus 330-200 even on this 2-hour flight. A small snack was served. The flight was uneventful.

I bought a round trip ticket online with my current passport number. When I arrived in Shanghai, I was held at the Customs for extra 20 or 30 minutes because the airline provided a passport number I used more than 10 years ago. My luggage was held at Pudong airport quite a few days. Each day, they said something different to me... When it's the time for me to go back, I was held again at PEK, because of the different passport number they kept in their system. Even though I explained to them how I purchased the ticket with my current passport number and I have no idea where the problem happened. They insisted that it was my own fault. My gmail did not work properly in China. I asked them for help by providing me the ticket agent contact info in the States. They said that they did not know. I should go where I bought my ticket. I had to spend hours to contact friends in the States to find the phone number of justfly.com. Then, I made international call to justfly for about hour to have the problem fixed. I did not provide any wrong info when purchasing the ticket. The problem was made between the airline and their agent. They, as professionals, could easily have the problem solved but they blamed the customer for the mistake. I had to spend so much extra time and money to cover their mistake, at the risk of missing my flight. That's the worst experience I ever had for international flight.

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

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 rentals 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,
