So my new job will have me traveling to major west-coast cities (including Vegas) 6-8 days per month, flying out of Reno/Tahoe. I've always enjoyed the "convenience" of checking my bag, though I know most savvy travelers swear by carry-on. Since I carry a laptop shoulder bag (man-purse) on board with me, I just prefer to check the clothes. Previously, my travel was 95% Reno-Las Vegas... hard to lose a bag. My new travel will have me transferring through Vegas and Phoenix for many flights, as Reno has done away with many direct options. Question... do you use a travel lock on your checked- luggage or do you use zip-ties or do you even bother? I know that when used they're only a slight deterrent and I'm aware of the pen in the zipper method of opening just about anything... just curious what you do and your experiences.
