I drove to the starting point.
Paid a bike shop to pack and ship it; I think the total for two bikes was about $475, which was more than I expected, but since I was on the other side of the country when the shop did the job, there wasn't much I could do about it.
There's a few downsides to a travel bike (S&S or similar). First, anything 700Cx28 or larger pretty much has to come off the rim. The racks and fenders, of course, must be removed. There's the $40-50 second bag charge on most of the worst (and largest) airlines. Finally, what do you do with the case when you get there? (or how do you get it there to meet you?)
All that said, I have been tempted by the Bike Friday system; pack the bike in the suitcase, your gear in a duffel. Remove the bike from the suitcase and assemble, put your gear in the suitcase on a trailer bed, and ride off into the sunset. I'd like to hear from anybody who's actually used this system if it works as well as the advertising reads.
