Website is just a standard one from AeroCRS, a company whose main product is minimal websites for airlines who can't afford to pay for a customised website. AeroCRS' main rival is Flexflight. Typically they are used by tiny start-up airlines with maybe one or two props serving less than 10 routes.
Harry - as someone who presumably spends a fair bit of time in the Philippines, you may wish to note the AeroCRS solution is also used by Sky Passada in the Philippines
For a new airline every penny really matters, and as long as a website can handle things like making new bookings, take payment and allow passengers to check-in, then it's good enough
