My guess is the restrictions announced this morning are very temporary (especially the ones for travelers heading from the UK to the US, who aren't even being allowed a handbag or any electronic items) but will probably still be in force on Saturday, when I'm flying home.
So, I've been mentally going over what shuffling I'll need to do in my luggage. Obviously I'll toss my tiny Swiss Army knife in the suitcase I'm checking, which I always do. But I'll have to do the same with the small hand lotion that's always in my laptop bag, and probably even the ChapStick that's always in my pocket. I won't bring aboard the water bottle that I'd normally take along, and I'll hope the airline is equipped to hand me a water bottle pretty quickly once I get on board. I'll make sure all my flasks are in my checked luggage, too.
Not being able to take aboard my hand lotion and water will be a minor inconvenience and is understandable, under the circumstances. I just hope the delays at the airports don't keep me from getting home Saturday night.
