Just to add a bit to texavia and to give you a realistic view on time and investment.

1-2 years to get all your ratings including CFI. Yes you will need your CFI that is the only realistic way to get your 1500hrs fast. Price for flt school can range from 45k to 100k +. based on if the program is only flying based or involves a degree. (ATP should cost around 55k-65k all said and done)

1-2 years instructing (CFI) to get to your 1500hrs because you will only walk out with maybe around 215hrs flt time from Flt school. All this while hoping your students don't get you violated and instructing your life to a person you recently meet.

Ok congrats you got the 1500hrs and a job with a regional carrier. (Yes there is no bypassing that but then maybe with the way things are going it might change or you might get a corporate gig). Regional pay is around 24k to 35k before tax first year and can go up to 55k by 4 to 5 years. More then likely you will not be based at home so get ready to spend on a crash pad and other essentials. Oh and don't forget about that Flt school lone unless your one of the lucky few that have the cash up front.

4-8 years in a regional then you might get a opportunity for the major airlines. Where you will take a slight pay cut to become a first officer because you already made captain in the regional airline you worked for unless you get hired from a regional first officer position to the FO position in the majors then you might make more rather then taking a paycut.

So about 10 years to make some descent money while making sure you will still be medically fit for that first class medical.

This is the reality of a pilot. Only thing I will say is it is definitely the best seat in the house.
