Cruises are heading to different ports because of the Baltimore bridge collapse, and Carnival says it's only taking a little loss

• The Baltimore bridge collapse will have a small impact on Carnival's bottom line.
• Carnival secured a temporary home port in Norfolk, Virginia, to minimize operational changes.
• Royal Caribbean and American Cruise Line's operations may also be affected.

Tuesday's Baltimore bridge collapse may marginally affect the world's largest cruise company.

All vessel traffic has been halted at Baltimore's port, stopping both containerships and cruise ships.
