Which really worth nothing.

Regarding AirAsia - again, this is LCC, with all consequences - you will have to pay for seat assignment, using of credit card during booking, checked luggage, even for a cup of water onboard.

But considering that it is just 45 min flight and assuming that you do not have tons of luggage - you should be fine. Just one word to mention - if you need to check luggage, buy luggage allowance during the booking process not later - anything later would cost you more, sometimes considerably.

But at the and AirAsia is quite reliable - had more than 30 flights over last 5 years and only one flight was delayed more than 4 hours. Delays of 30min-1h are quite common and it is normal.
