I changed careers and got my private pilot's license at 40. I am now about to turn 46, and I have 4000 hours, and 3 type ratings. I just finished a contract in Saudi Arabia that paid $9000 USD a month, with housing and car provided. 30 is nowhere near being to old. The reason I was able to advance quickly is because I have no attachments, and I am free to take jobs anywhere in the world. Also, the job market for pilots really oscillates between feast and famine. I was able to ride the job market to a pretty high peak before the economy crashed. Now it seems the aviation job market is on the verge of a comeback. If you can quickly work your way up to a commercial multiengine license, you may find many opportunities available in the next few years. I say go for it.
