The food is always bad, and they didn’t allow use of electronics (phones, and they didn’t like me using my iPod I suppose because it looks like a phone?) on a 6 hr international flight when there was NO individual entertainment and no screens. What’s worse is I went into the bathroom right after a flight attendant and there was urine all over the seat! She either did it and left it, or she saw it and hovered over it, leaving it for the next person. Not classy.

The attendants were nice and as helpful as they could be with limited English.

The seats were the equivalent of a small puddle jumper plane in the US. Not very well padded and uncomfortable. I took a small pillow for my back and that helped. You aren’t allowed to use your phone at all during the entire flight. It was next to impossible to choose a seat in advance.

CX still has good offerings on flights from their home in Hong Kong to other destinations.

However, CX for International Regional is, in no way, comparable to their better long-haul routes. That being said, the entire airline has lost its luster like their home country is losing their value with prices going up and value for-the-dollar going down.

The crew were friendly although some of the announcement was not clear.

We had bad experience with the airline because our luggage was not to be found at Langkawi airport and we had make a report. Fortunately about 8 hours later our luggage was sent to our resort which we stayed. (we arrived Langkawi airport around 3pm, we were told by the officer that our luggage will be sent to our resort at 7pm but it came at 11pm instead) The snacks could have been better. Besides the salted peanuts, it would be better to add biscuits or a slice of cake. The orange juice is good but maybe if we are given choice of warm drink (tea or coffee) it would be great.

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.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don'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.

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.
