I don't fly, but my brother does.
It took him almost 8 years before he got where he is now, and that is a job as a corporate pilot for a manufacturing company.
He went to college, and got his aviation degree, and spent a few years getting additional flight training so he could fly business jets, turbo props, fly passengers, instruct, ect. it took him that long because of not only the cost of the initial college, but flight training as well. He had to work during college, and skip quarters because he was out of money.
He finally did it, and has been working as a corporate pilot since 2001. Prior to that, he was a flight instructor for a few years for a flying service, and he still instructs on the side.
From what I've seen and heard from my bro, it takes patience, time, and money to get where you want to be. You have to log LOTS of flight hours to be certified in different areas, and that gets expensive if you have to pay for the training yourself. My bro wanted to fly for the airlines, but he doesn't think he ever will; he's getting too old, and he enjoys his current job way too much.
