Poor, poor Squale,
Somebody told you there was big money in aviation? Sorry, is it too late for a refund? I think you're going to starve more at the airlines that anywhere else too, at least in the beginning. You're going to start off as a flight instructor most likely, at approximately $12k - $15k per year (try starting to pay off those loans and it's HELLO TOP RAMEN!! You'll get a pay raise when you go to the airlines at about $18k - $20k per year. After 20 years in the company you'll be set though, that is if the airlines haven't drstically reduced pilot wages yet.
Really though, you'll be so dying to get PAID to fly that you'll MAKE your CFI job work, whatever it takes i.e. 6 roommates, top ramen, second mortgage, whatever. When you get the time put in and get hired by a regional you will get a small pay increase which will be just like icing on the cake, or tassles on the stripper, whatever catch phrase you prefer. One day you will get hired by a major and you will be able to afford those nice things that you're wife couldn't talk you into before.
My problem is I was hired to fly for a regional (read slight pay increase from CFI) then 9-11 happened and I got my training date cancelled. In the meantime I got a corporate job that pays a hell of a lot better and I don't want to take a pay cut to go to the airlines (never really wanted to be a bus driver in the first place. . .I want to be a limo driver) The way I plan on making money at the whole deal is getting on with a fractional (read slight pay DECREASE) to get some type ratings in some bigger airplanes. These people with time and types in big corporate airplanes can eventually command a six-figure salary.
The short answer to your question (that should have been a separate thread) is "yes" there are a million ways to skin that proverbial cat, and the way you end up doing it will most likely be different from the way I do it. it's peanuts in the beginning when compared to the investment you made, but remember it's because you love to fly (or are a glutton for punishment).
Just do us all a big favor, take the CFI job for the sh!tty pay, but don't whore yourself out to that corporation for a little more than you're making as a CFI when they come asking. it undercuts us professional pilots trying to make a living, yes we love to fly too but also love the qulaity of life we've built (are building) for ourselves and nobody likes a scab. you don't have to cross a picket line to be labeled a scab either. Good luck, friend.
