I travel a lot, often away three nights a week.
If I'm checking a bag I bring the Feather DX folding and a few spare blades. Like Obie I will also have a DE, in my case an early Super Speed TTO or a Red Tip Super Speed.
Ditto if I travel to the same place every week, I find a way to safely leave a Feather "something" - the Hotel that I travel to now gave me a safety deposit box. They don't use them since the rooms now have safes and the Manager let me "rent" one.
If I can't check or stow its a Cart, but I bring my travel brush and a stick of something.
And your Straight may just need a proper honing to get it Shave ready, and check the Wiki for help with stropping.
To paraphrase Obie - "comfort first" - for many a well prepared conventional Straight is the most comfortable shave..(YMMV)
The Feather that Obie and I speak off offer incredible edges with the the weight and balance of a solid 6/8 conventional straight.
Smooth shaving...
