Only two check-in counters were available. The waiting time for check in was, therefore, quite long, and the time was very tight until the boarding. The seat allocation was horrible, and I was surrounded by nasty neighbors, who were chatting throughout the 10+hour flight, even after my verbal warning, not to mention the way children were taken care of. I am not blaming children making noise. I am blaming the lack of control over the parents who bring noisy toys for children and play videos loud enough to disturb the neighbor's sleep throughout the flight.

good it was not a long flight.

The crew was a bit negligent. They passed me when serving the food just because the aisle seat passenger next to me was served his special meal earlier, so they did not notice that the passenger at the window seat (which was me) had no tray in front of him when running the regular meal service. Isn't this sloppy !? Problem is that once they passed you, it's hard to get their attention, as they are always in a hurry, and not looking over the cabin just to check if someone needs something or wants to call on them for any reason, and there are no attendant calling buttons available. So you have to wait until they come by your seat again. Finally I got my meal with apologies 15 minutes later, but the experience was already ruined and the negative impression built.. Also, when departing from Taipei, the boarding process was a bit disorganized, compared with the one we had in Vancouver. As for as the entertainment, the LCD monitor at my seat was pretty worn out, with very poor contrast, making it difficult to watch a movie or read information. Same airline with two opposing experiences: Vancouver-to-Taipei very good, Taipei-to-Manila: poor.

Extra leg room in emergency exit row They actually played a movie that was in English. Not the first time I have flown China Southern, but the first time I had air control above. This is something I feel makes flight a bit more comfortable.

Food is terrible. They ran out of wine during first beverage service. Exit row passengers are not permitted to keep items under seat. Flight was delayed at take off and perhaps in route because we were over an hour off of schedule. Aircraft always had a line for the bathroom, two is not enough for amount of people and duration of flight. I do not know if there was bathroom in front, it was sectioned off.

This ridiculous airline and it's rude, obnoxious staff in Chengdu made a mockery of my friend and I (two 21 year old American girls traveling alone). We had booked round trip tickets back in October 2017 that included a 1 hour layover in Chengdu first, then a 7 hour layover in Shanghai on our way to Bangkok for a trip in Thailand. That was fine with us. Then all of a sudden it changed to a 6 hour layover in Chengdu then an 18 HOUR layover in Shanghai. We decided to deal with it and get a hotel room in Shanghai, no big deal. After a great trip in Thailand and leaving fine from Bangkok to our first layover in Chengdu, that is where the nightmare started. First off, going through Chengdu customs, I don't know if it is because Americans do not travel through there a lot, but the officers pulled us aside and were passing around our American passports around their staff, taking pictures of them with Iphones before handing us "in-transit" paperwork to fill out. As weird as that was, no one really seemed to speak english and we just wanted to get away from them and get through. When we went to the check in counter, they handed me a boarding pass for our flight at 1:50 that afternoon, but then proceeded to tell my friend that she wasn't on a flight until the next morning at 7 am out of Chengdu and our original connecting flight out of Shanghai at 11:50 the next morning was now at 8 pm for her. What could have been simply fixed like it WAS after calling priceline and our travel agent, the staff at the ticket counter and a representative over the phone made our lives living hell. They barely spoke english and the ones that did were very rude to us, saying that they couldn't help us and put us on the phone with China Eastern. FOR AN HOUR AND A HALF we were on the phone with a representative who was talking us in circles, telling us that there were no available seats on the 1:50 and that he could get her on the next 3:45 out of Chengdu, then put us on hold to come back and say he couldn't only change 1 domestic flight in China, but would have to cancel her flight to NY. When offering to pay to just DO IT and get out of china, he said that if he were to cancel it and take our credit card info, it "may or may not go through" and if it didn't she would be stuck with no flights. When asked how that made any sense, he proceeds to say" Because miss, our system sucks," and other rude things like "Why can't you just keep your flight and meet your friend in NY." then him along with a rude ticket counter guy say that he could help us if we took 5,000 yuan out of the bank and paid them cash. TRYING TO SCAM US. After all this drama a simple call to priceline was able to fix the problem no payment involved, and there WERE available seats on all the flights and a domestic flight could be changed. LYING, SCAMMING, RUDE, individuals. Definitely worth a little more money to take any other airline BUT THIS ONE.

Delayed flight after waiting for hours in Hongkong. The male flight attendant was inefficient. Did not check on passenger’s concern even after it was brought to his attention. Simple request for water took forever to arrive. Did not like meal so requested a cup of noodle instead but the noodle never arrived. It is stated in their menu that snacks like cup of noodle is available through out the flight but only when you stand up and get it from them. Very poor service. I will never fly Cathay Pacific again. That will be the first and the last.

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.
