used to work for a container shipper, there is absolutely zero intra-US transportation via container vessels. The multiple US port calls in a string such as NY - NFK - SAV are discharge - discharge - load or something of the variant. its not picking up containers at NY and discharging same containers in SAV. besides, I can't think of any use-cases where container shipping within US would be sensible. US company supply chains aren't designed in a way where procurement activities are dispersed and could benefit from intra-US container shipping. unless someone can think of a company? another note: IIRC theres a lot of traffic that discharges at LA and rails to HOU. even with the expanded canal, this is the most cost efficient way to get cargo from asia to houston. trans-pacific vessels are > 10k TEU so if a supplier wanted to go through panama canal, you'd have to use smaller trans-pacific vessel which would raise shippers unit cost thus raising the suppliers cost. if you're a company that relies heavily on asian imports, your facilities are typically located on the west coast to avoid extra transportation cost anyway. i don't think this news is that impactful
