I want to become a Boeing 757 pilot, how much will it cost to get my license to fly for an airline?

If you join the air force, then nothing. Many commercial pilots started in the air force. In order to fly something that big, they'd want a person with a lot of flight time.

But you might end up driving an air force bus rather than a plane, if you don't measure up. That's the deuce of it in a nutshell.

Well....I don't me to put you down but by the time you qualify to be a fully trained pilot the 757 will NOT be in active service it's already out of production.

The cost to do that sort of training is simply astronomical! Figure well over $1 million. The vast majority of airline pilots get their training as members of the military services.

You have to go to flight school, which is usually at a college. If you want to know a good flight school I recommend the University of Nebraska at Omaha's Aviation Academy. It's really good, in my opinion.
