Many of my colleagues who travel frequently check their luggage. My boss, who is a United 1K and Global Services, always checks his luggage. He does this despite having had his luggage lost several times and having itmes stolen from his checked luggage (by TSA?).

I, on the other hand, always carry on everything in my 20" rollaboard and laptop bag, even when taking 2-week trips overseas. I often avail myself of hotel laundry services.

I used to check luggage, but I got tired of having my bags repeatedly damaged and soiled by the airlines. Then when the TSA decided that they can open (and sometimes pilfer) your luggage anytime they want, I decided to take only carry-ons on all my trips.
