Speedy,
I noticed your name here from your posts on the ME forum. I'll get in before the chorus here crucifies you, but you need to do a lot more research on the aviation industry, particularly in North America.
Making grandiose plans about which particular airline you are going to work for and when, before you have even started flight training, shows a naivety that needs some explanation. I am not having a go at you. I am trying to save you a world of disappointment.
At the moment EVERY major US carrier is furloughing pilots. That means guys loosing their jobs, but retaining the right to go back when (IF!!) things pick up. Some of those guys only recently got back after several years of being on furlough, before AGAIN finding themselves on the street.
Once the majors do start taking new pilots again (and it will be years) there will be thousands of highly experienced pilots who having been flying regional, corporate and GA lining up for the jobs. A quick three years in a regional and then into Delta isn't likely to happen any time in the next couple of decades.
At EK we are overwhelmed with application from high hour US pilots both from the majors (because they have been laid off, gone broke or saw no future there) as well as many regional Captains and Training Captains who who have come to be F/Os because they can't see themselves EVER getting into a major.
You've chosen a tough game, and if you go to the U/S, a very tough field to play on!!
As a European citizen you would be much better off looking at doing an integrated JAR ATP course, preferably tied up with an airline. Have a look at easyJet, Sterling and Flybe as examples.
If the costs there are too high, you are stuck with the well
pr oven route of self-sponsor, and work as an instructor or air taxi pilot to get the necessary experience.
Sorry if this sounds negative, but it's better to hear the truth from me than a bunch of sales talk from a school trying to part you from your money.
Best of luck.
