I’ve flown with a lot of airlines in every class. This was an economy class flight and still the food was better than I’ve received in business class on American. The seat was comfortable, the entertainment options varied and extensive and the cabin team were amazing. They clean the bathrooms between uses. Seriously how do other airlines still exist?

No free upgrade? ;-). But that’s unreasonable. I love this airline having not flown with them for 4 years I don’t understand why!

Javier the flight attendant was so welcoming and attentive. Flight got l fit late, but arrived on time. Service was efficient and respectful. Was not as crowded as prior flight and was able to eat the meal

Time of flight really sucked. 4:00 AM departure meant arriving at 1.00 AM. Tough way to start a day

paid extra for legroom but the legroom seats have a big disadvantage of no place to put things you need on a long flight.

The weather delay was understandable - boarded flight 19 hours later than scheduled, but then there was a problem with the engine, that delayed us further by 5 hours. We had to sit on the aircraft for 5 extra hours on top of what was already an extra long flight. 21 hours on the plane - and there was no coffee! Being on a plane for that long, you should be able to get a cup of coffee. Staff seemed annoyed as well and were overall a bit rude. Wine tasted like acid.

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.

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,
