Due to a$$holes in the airport we missed a flight from Minneapolis to Atlanta to Jo a couple years ago, ended up going through London.
At the gate I'm flagged as traveling with firearms and was asked if I had permits. Scared the crap out of me as NO I did not and explained the situation. Showed them my permits for Africa and the lady was very polite and assisted me in filling out the paper work and went on our way.
I've been through London a few times in normal travel and I'd rather deal with them any day than most of the people here stateside who don't give a crap about you or if you miss a flight, etc.
