You want to go $60,000 into debt (you're not going to be able to complete everything in the minimum time required, especially if you're taking time away) for a $20,000 job in which you'll be away from your family and friends all the time?

Also consider that you won't be able to get a job right out of ATP at this time. Sure, last year people were getting hired at the less desirable regionals with 400 total time. However you have somewhere around 1000 regional pilots currently furloughed. The few airlines that are hiring have their pick of hundreds of people with much more experience than what you have.

If you want to do it, I'd save my money, find a nearby FBO that costs less and work at your own pace rather than paying the premium that comes with the ATP name.
