Lufthansa apparently makes it easy to fly with your bike.

You still have to pay a baggage fee ($150 for an intercontinental flight), but you don't have to box your bike.  You don't even have to take the pedals off. I guess you just wheel your bike up to the baggage desk and check it in?

This is at least a double convenience; no disassembly/reassembly of the bike and no bike box/travel case to deal with.
