With the firm orders made in Farnborough, I do not think Air Asia is in a so bad situation....
About low hours pilots, the question is not only to accumulate flight hours but to be trained up to certain standards. You can accumulate 1000 hours of cross country and to be unable to fly instruments as per required accuracy.
Hours is one issue, what you are doing during those training hours is another one and probably, the most important one.

good luck
