Thank you. You are more than qualified for a position here. As long as you do not have any disqualifying criminal offenses and you have no major financial difficulties, you should be fine getting in.
As a pointer, you may want to go to www.opm.gov and download SF form 85-P. It's the application for Public Trust Position. I cannot remember if the form is still required, but it was at the time I entered. It is quite lengthy so you may want to start early.

Out of curiosity, which airport are you interested in?
(if you don't want potential backlash from our frequent flyers, you can PM that answer. Some folks here are really ticked at some airports, if not all of them.)
