Surprisingly enough, it seems to be extremely hard to get seats in France. I've asked many many times before embarking in this... Anyway, now I have them here!
Shipment is currently, here in Herndon, VA (20170) and needs to go to France (55800). I can drive to Baltimore (Port of), or one of the local airport (IAD preferred or BWI). In France, I can get them picked up at the airport (CDG) or in Le Havre (Port).
There is a ton of ship that do Baltimore -> Le Havre, which I am guessing would be the most economical method (and dropping directly at port and picking up at port), but I'm not sure who to reach out to to get onto one of those ships. Moving companies maybe?
