Seems like a saw a news story on just that awhile back. Maybe it was when airlines started charging for checked bags, but I seem to remember that for many fliers, depending upon starting and ending points, shipping UPS was cheaper - and virtually guaranteed.
I looked into this quite a while back. You have to have a lot of certainty about where and when you're going for it to work out well. Even then, it takes an extra trip to the shipper a couple of days before you leave. Much better suited for the occasional well-planned vacation than for frequent and short duration business trips.
