A clear divergence has opened up between US coasts this peak season: West Coast ports are seeing more available capacity as additional vessels entered key services, while East Coast, Gulf, and Pacific Northwest capacity remains noticeably tighter.
What's Behind the Split
- Carrier alliances have deployed extra loader vessels specifically on West Coast-facing transpacific services
- Panama Canal draft restrictions continue to cap effective capacity on East Coast and Gulf-bound routes that transit the canal
- Front-loaded volume earlier in the year has begun to ease on some West Coast lanes as the initial rush works through the system
What It Means for Routing Decisions
Shippers with flexibility on discharge port may find better rates and more reliable space by routing through West Coast gateways and moving cargo inland by rail or truck, rather than defaulting to a direct East Coast call that now carries a capacity premium.
The 'right' discharge port isn't fixed — it moves with capacity conditions, and right now those conditions favor the West Coast more than they have in months.
