Airasia is an international airline that offers primarily destinations to and across Asia, to cities like Bali, Singapore, Bangkok, The Philippines, and Phuket. You get to pick where you sit for a small fee, or you'll be assigned to one at random. There is also a Quiet Zone onboard and a flatbed so you can catch some while inflight! Or, choose hot seats with extra legroom, or twin seats to sit snuggled up and close to your loved one.
Their loyalty program is called BIG Loyalty, with a simple sign up process and the chance to redeem flights. Everyone is allowed one carry on item, and business class passengers are provided a baggage allowance for checked bags.
