Melissa,
I've seen several of the threads you've posted. It's good to see someone trying to get an idea of what life as an airline pilot entails before getting in a lot of debt without other tangible skills and finding themselves stuck in a career they hate.
You should know, however, the way things are today are unlikely the way they will be when you finish flight training (for better or worse.) When I got out of school, the model seemed to be go to a regional, upgrade in two years or less, get your TPIC time and go to a major. Then in 2007/2008, all that changed. There are many of us who are 6+ year FOs or 10 + year CAs at regionals who can't get out. This is a very fickle, unpredictable industry. If your timing is right, you can have a great career, don't get me wrong. But if it's not, you may find yourself grinding out a less than desirable living at a bottom tier airline with no hope of escape save a career change and/or more schooling.
I hope everything works out for you better than it has for me. If it's your dream and you won't be happy doing anything else, by all means go for it, but know that you have a very wide range of possibilities with regard to how your career may progress.
