All 3 in the UK have been fishing through CVs in the last few months... and on the otherside of the NS there are opportunities if you speak a Scandinavian language.
However, if you do your IR and they aren't hiring anyone for a while, what will you do? A few positioning flights?
If you get an FI at least you can always earn some cash that way, and keep yourself current. Maybe build up to 1,000 hours so the NS operators take a little more notice, and during that time save for an IR?
Just a thought, because with 450 hours an IR is a gamble which may (hopefully) pay off, or may leave you high and dry.... unless of course you already have the FI
