Few industries eat up capital like airlines, and the sharp swings between profit and loss they suffer. However, Asia's promise and the strong backers of new airlines, especially in India, outweigh the risks for many financiers.
All told, Asia's aircraft orders and options book tops 500 this year. Airlines will need to find US$15 billion to US$20 billion to pay for all those aircraft.
A growing market, a strong business plan and cashed-up backers all make raising money easier, and if Asia is one thing, it's a growing market.
'I think if you come with a piece of paper starting an airline with 100 planes you might face problems. If you have a proven track record it's a lot easier,' says Tony Fernandes, the chief executive of AirAsia.
However, not all options will become firm orders, and some firm orders can turn sour.
'There are a lot of people placing speculative orders without at the same time putting the financing in place to pay for the aircraft,' says Robert Martin, Singapore Aircraft Leasing Enterprise's managing director.
When they order, many airlines have still not tied-down financing.
