Gettting ready to leave tomorrow, I was just cleaning out a bag tonight that I carried on from BOS EWR JFK AMS FRA EWR BOS in mid June then late June from BOS DTW KIX TPE KIX DTW BOS and found a plastic corkscrew in one of the inner pouches of the bag. The plastic cover of the corkscrew slides through an opening at the top of the screw.
I didn't mean to do it, but no one stopped me. Maybe because it was plastic, it didn't show.
From the old days, I used to place corkscrews in all my bags because I hated being caught somehwere around the world without one. Will have to check all my bags.
