Above all, good prices. Because most AirAsia flights are short-haul anyway, I don't think you'll miss having the snacks/drinks/TV of regular airlines. Nice leather seats too. Ticketless booking is nice, just go there with proof of ID, no need to worry about having left tix at home.
Only problem is the first come, first served seating system, it leads to some big rushes at the gate. When they announce it's time for boarding, everyone makes a dash for the entrance, and it's amazing how much queue cutting and just plain general rudeness goes on. I've learnt that Malaysians are just as kiasu as Singaporeans
On the whole though, it's all worth it for the price.
the booking and ticket purchase is easy, Pay over internet.
Most importantly, it is much much cheaper compare to MAS.
If u pay for MAS (much much more expensive), there are only 2 air-stewardness and give u a glass of orange juice.
Air Asia serve u nothing for free and there is only 1 stewardness.
But it is ok. Take for example, Penang to KL, less than 30 mins. Once u tighten up your belt. And look around the passenger, u are almost about to land. No big fuss about no free dirnk. U can always buy a can of coke for RM3.
but the ticket fares that u have saved, is more then RM300.
I travelled by AirAsia from KL to Labuan and back early this month. The flight was 2hrs+ and was not full. I paid RM79.99 per flight. I had a row of seats to myself and enjoyed the nice view of South China Sea with beautiful islands like tioman, the Anambas islands and natuna island. The sandwiches taste ok for RM5, at least got something to bite while waiting for time to past.
Rating: Very value for money, especially for travel to east malaysia. Note that to get the lowest fare, you have to book a month in advance and no refund or change is allowed. If there are more than 1 flight a day to the destination, only some timings will have the lowest fare.
