I often travel overseas on business but usually for less than a week at a time. I know how to pack efficiently and fit it all in a briefcase and roller bag so I never, ever, check luggage...Too many bad experiences there. On my return to the States, I'm often greeted by the customs officer who's surprised that I'm not carrying more luggage. Usually, it's not a problem but my last trip was longer than usual (10 days) and this time the luggage question was asked in a very skeptical manner, my answer met with disbelief, and it was followed by a detailed search and questioning. The process added about 15 minutes to my arrival and negated about half the benefit I usually get by not checking my bag, so I'm trying to figure out if I did something I could avoid in the future. I'm always very respectful to the immigration/customs officers and never offer any sass or lame humor, just the facts. Any idea from the group whether the lack of checked baggage on an extended trip is one of the major triggers for a search?
