Airlines shrink carry-on bag size

[Paul F.]

I wonder when the first modern trans-atlantic and trans-pacific liners are going to be built... Not a "cruise ship" with lots of luxury, but a passenger ship that will cost less than a business class seat with a gazillion dollars in luggage, rules, taking off your shoes at the airport, etc...
I'd be up for a trip across the atlantic that takes 5 days, if I can bring a reasonable about a luggage for a 20 day trip!

Just kind of an idle thought...
