Did you ever think that the reason banks aren't so quick to give out loans is because you most likely will not be able to pay them back?
Even though you may believe you are destined to fly, the reality is there are thousands and thousands of people out there a lot of them are unemplyed and extremely heavily in debt with no sign of work on the horizon even still, pay isn't all that good to justify a huge loan or remortgaging your house.
Look at any flight magazine, the amount of advertisements for schools willing to take your money telling you that you will be on a fast track to an airline job is beyond a joke, it seems like there are more now then ever.
In Florida there are billboard advertisements along the Interstates for Delta connections with promises of airline jobs, its nearly funny when you know the reality of the situation.
Flying is nice but dont remortgage your house or get so far in debt that you cannot enjoy other things in life.
