The plane didn't crash.

Boarding was late and terribly disorganized - just a person yelling row numbers who could barely be heard. The airline makes you pay for water, which is simply inhuman - at least cattle in transport are given free water from time to time. It was a five-hour flight at night but we couldn't put the seats back to relax - the exit row was behind us and they've got the seats crammed in so tight together that they don't give the exit row any extra room to accommodate this, like most airlines. There are ads plastered all over the storage compartments. Recorded announcements threatened us with dire consequences if we stole the life vests (is that a thing people do?!). Everything looks cruddy, dingy and old. It feels like a cheap city bus, but in the air. At the end of the flight the crew walked through fumigating the cabin with spray cans of who-the-hell-knows-what and we had to breathe THAT in. We won't even consider Air Asia again unless there are literally no other possible choices. Just awful.

The food is shockingly decent. Yeah you have to pay cash and it’s not convenient, but the food is edible and there is lots of variety.

AirAsia sucks balls. Or at least, it was fine leaving Singapore, but returning from a crappy small town airport to it was a fraudulent nightmare. We were told to check in online and add baggage at least two days before flying to avoid excessive baggage fees. So we paid them the first time, no problem. But AirAsias website is clearly coded by bricks with fingers. Because 6,5,4, and 3 days prior, it says such service is unavailable. Okay, we’ll do it at the airport then, it’ll be nice and easy just like at Changi. Only at this crappy subpar excuse for an airport, they live by no rules and want to charge $300USD - more than double what was charged at Changi - for two 20kg bags. 20kg, which my boarding pass and my booking both say we are entitled to, is suddenly 5kg in excess, so they want to screw your American wallet hard, long, and good because even if you had a good time, chances are you will never pass through the half baked gas station that is Langkawi again. Oh yeah and don’t bother paying for the WiFi - they get you good there too - 10mb which is basically a couple jpegs but you won’t get squat anyway. Literally nothing, and then suddenly your puny 10mb has disappeared, along with your money and what’s left of AirAsias credibility.

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

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
