Tiger Airways, Singapore
Tiger airways is a singaporian budget airline that connects Singapore with several Asian countries aswell as Australia.
They have very competitive fares and you should check them out for good deals if going to or from Singapore.
It´s a budget airline so you will need to pay for food and drink there, but i have been quite happy with their seats and their service when i have flown them and i consider them quite a lot better than most european budget airlines for instance.
My wife and I rode for the first time on Tiger Air to Singapore from the Philippines and it was worth it! We were able to avail of one of their offers and our round trip fare (not including taxes and insurance) was only US$23.64 for both of us. You will be arriving at their Budget Terminal, which is a very basic airport; size is just right but most of the necessities are there. You can even "surf" on one of their computers for free for 15 minutes! On Tiger Air, on the other hand, you will have to buy for the meals or drinks they offer on the plane. The prices are not that bad, S$8 for a small hot meal served on a styrofoam and the softdrinks are around S$2, if I'm not mistaken. Just eat a heavy meal before boarding. And a reminder to potential passengers, the weight limit for check in luggage is strictly 15kg per individual. I suggest you bring a carry-on bag and place your extra stuff there.
