One of the biggest isues when it comes to looking at jobs overseas for US pilots, is that it's normal for most companies to stamp your logbook every month/year to ensure your hours match the company records.

You'll be doing yourself a favour if you can get the Feds or your CP to put some kind of stamp/business card in your logbook and sign it.

Also, when I visited the UK CAA a few years back about the possibility of a UK validation, they went over my logbooks with a fine tooth pick and queried everything thay weren't sure about. The guy who dealt with it made the remark that they (CAA) like to see information for every leg! Anything else and they start to ask questions.

I'm guessing you're probably going for the Flybe gig in the UK? In which case the main problem is that the Brits like to feel superior and think that US pilots are cowboys. Make sure your logbook is clear, neat and don't give them any reason to question your experience.

Good Luck.
