Wow. If the Jones Act could be waived, that could be wonderful for cruise lines.
I can see it now. LAX to SFO to Hawaii about a 14 day cruise. Then reverse it back. Or SEA to SFO, to LAX to San Diego
MIA to NOLA, to Galveston TX about 14 days with lots of stops a long the way.
Portland Maine to Miami
Oh my. The itinerary's could be endless and you won't really need a passport.
