duchy....if you are getting back on the same plane, you have too much....i usually have a change of garments, a book [i cant read more than 1 book on a turn around mr] cash, cc's, passport, no laptop or cellphone, snacks [sometimes pilfered from the ac]....

sometimes, i don't need the rollaboard pull toy....but can do w/ a shoulder bag...

for a 2-3 day stay when the fare requires it, i can still get by w/the pull toy, but do take a camera...

good luck...
