Yes Coast Guard Pilots transition to the airlines but only after finishing their commitment. Right now it is 8 years from the completion of flight school and 3 years for OCS. Also you have to be a fixed wing pilot because the majority of Coast Guard pilots are helo bubbas which doesn't count for airlines.

All Coast Guard pilots AV8R's are commisioned officers. Soooo that means you need to go to Officer Candidate School (OCS) and then go to Navy Flight school. It is important to know that you would be an Officer first and a pilot second. There are several different paths to take to get to flight school and they range from AVCAD which guarentees flight school upon completion of OCS to applying for flight school and being accepted before making LT/O-3 which is typically 4 years from completion of OCS.

Your local recruiter should be able to help you get the application process going and tell you more about the current programs available.

Good luck and let me know if you have any other questions.
