Tickets should be printed for all the flights, instead of having to go to the ticket counter each time. Luggage needs to be shipped all the way through. People need better English proficiency, they were useless.

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.

Air New Zealand needs to manage double door boarding a little differently - a ticket checker needs to be at the split point - to streams of passengers trying to find their seat in opposite directions just doesn't work.

We flew Air Canada’s Economy Plus from Vancouver to Sydney and Air New Zealand’s Economy Plus from Auckland back to Vancouver. NZ’s Economy Plus product is far and above AC’s. Everything from the welcome, to the meal, to the level of service is great. I really felt that NZ treated the Econ Plus cabin as distinct from Economy (including having 2 dedicated washrooms), whereas on AC it felt like we were merely Economy with better seats. I compare NZ and AC because we were so genuinely impressed with what we purchased. We would definitely book NZ Econ Plus again, and the January seat sale is a great time to do so!

I can’t think of anything I didn’t like. NZ gets this product right.

I felt I was gouged on my 2nd bag fee with an outrageous cost of $200.00 aud or $150.00US. It only weighed 20lbs. as well.

Most of the staff was very helpful and accommodating. On the first leg of the flight one of the attendants even suggested a wine with dinner, a very kind gesture.

When my husband and I went to check in for our flight at the desk we had to wait very long time to get checked in. We noticed that one of the girls was in training, which is understandable but just inconvenient. We are both very patient people but this just made us nervous because our first flight on Air China to Japan on 10/26/17 was very delayed and caused us to have to literally run and still go through a rigorous security check. We were not rushed through the line even though we had nothing to do with our flight being delayed on our second leg. We then had to wait in another long line for security even after arriving into China on our flight back. There was also someone on board before take off with a medical problem and we could tell that some of the patrons started getting a bit aggressive or irritable. I don’t think the crew could’ve done much in that regard but wish the issue had been resolved a little quicker. I believe it was a 40 minute delay in take off.

All our checked bags, all of them, never made it. We are still waiting. Very cramped on totally full flight.

The food was good for airplane food.

It makes no sense to not allow the use of any electronics during take off and landing. My E reader doesn't even use a cell signal, but I couldn't have it out. Also, not allowing cell phones at ANY time during the flight, even in airplane mode, is ridiculous because tablets, which can have cell signals, are allowed. Air China is just frustrating.

Doesn't matter if your economy or first class. First one to the gate gets in. Good for me because I always fly economy.

Typical Chinese service, poor. Will never fly Air China ever again. Only reason why I book the ticket because it was cheap, now I know why.

I have flown with Air China before and had a bad experience. They are improving everything from customer service to in-flight amenities. Transfers in Beijing are still a problem with zero efficiency.

They don't honor seat selection when booking but attendant at gate helped and was very understanding.

The crew, the flight, the pilot to cabin communications, the food, USB hookup, and the movie selection was amazing. I am so happy that I flew Japan Airlines on my return trip. I would highly recommend them for your travels.

My original flight was late and pushed my entire schedule back. I had 15 minutes to deplane and get to my connecting flight. This caused a lot of stress on me however, the Japan airlones Crew escorted me (we ran as fast as we could) to my next flight so that I wouldn’t miss it. I boarded with 1 minute to spare which is way too close for my comfort.

A Japan Airlines employee escorted me every step of the way to ensure that I made my connecting flight from Tokyo to San Diego because I only had an hour and ten minute layover and this can be challenging when you’re in a foreign country. I cannot thank Japan Airlines enough for how easy they made traveling and how comfortable they made me feel. I Highly recommend flying Japan Airlines for your travels.

If they know that the flight is about to delayed then they must wait for the passengers for connecting flights!

Kayak or JustFly put wrong ID number whole booking the flight. First 2 segment I had no issues buy 3rd segment they denied to check me in and almost forced me to buy a new ticket. Check in Crew was rude and would speak to me in Chinese. I am a foreigner who doesn't understand English. They wanted me to call my booking agent in Canada, it was mid night in Canada.

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.
