Totally agree with LP. The Brompton is the only one you are liable to get away with checking without a charge *provided that* [edit for clarity] you only want to fold the bike. Some people have toured on them, but they don't ride as well as other bikes. However, all other bikes require at least some disassembly. There is a case that will swallow the Brompton whole. (Anyone have a link?) I have talked to people on the road that put in serious miles on those bikes. Maybe it's just a bit of getting used to.
The one strong point is the tires. I use Brompton Green tires for commuting on my 349 Birdy. These are probably among the best commuting tires I've ever used.
If you can manage to take the tires off and pull the seatpost out, Birdies and many Dahon models fit into an airline legal suitcase without tools. But it does take some getting used to.
