Re: Background check question (for those who have already do
The more "unique" things in your background, the longer it'll take. That means more addresses, more places you've worked, any criminal convictions, any medical questions they may have, anybody who takes their time returning the reference letters... it all can drag it out.
If you're at around four or five months, that's not too unusual. You can always try giving Aviation Careers a call to ask if they've heard anything, although they aren't the ones who're processing it. While it's easier said than done, don't worry too much... they'll contact you if they need anything, and unlike other parts of the process, they haven't lost your stuff or forgotten about you.
