Hi shorty,
I'm short, too, - 160cm, which are 5'2, right? - but being short shouldn't be a big problem. indeed, it may be an advantage while flying, because of G force and blood circulation in our body.
Some time ago I started a thread about this issue, and except the possible social problem, there shouldn't be others. In fact, I've been told through PM that being 5'2 is not a problem. Who sent me the PM is a 767 captain, and he's 159cm...
Then, give a look to British Ariways minimal height requirements: 1.57m!
