normantr:I just got back from Maui, and boy do they hate Americans over there. And the exchange rate was just horrible, the average dinner for two was nearly $80 USD. My next vacation is going to keep me in the USA.
Yeah, it's 120 puka shells per one USD, the bone thru my nose makes it tough to shave, the grass skirt itches like crazy, and "brah, us guys talk dakine pidgin ladat"...
Seriously, I can see needing a passport if for some bizzare reason your flight mutates into an international one -- maybe bouncing to Mexico or Canada and coming back or maybe a stopover has you change planes from a domestic to a foreign-flagged carrier (?). (Canadians are supposed to be exempt but they still have to prove citizenship which means a passport anyway -- bureaucratic double-talk at its best.)
