No blade on carry on, and the AS may have to be less than 3.5 oz in it's original container. If there is still time, you should probably mail your blade to the family that you will bum the goo from.
I have only traveled once, for business. I took my Black Beauty short handle, and VDH boar brush. So when I got to my destination I had to go hunting for blades. I found a family dollar store, and bought a 5 pack of crap blades for $1, and a wannabe Brut AS for like $3 lol. I asked the front desk of the hotel if they had shaving cream, and they gave me 2 little packets of shave 'lotion'. I mixed it with the shea butter bar soap they provide, and whipped up a B- lather lmao.
How do you travel with your shave gear?
