Thanks REDBAGSRAMBLER for the insight. I'll be calling the airlines shortly.
JOHNJ80 mentioned his experience with the Airport Ninja bike case and that has piqued my interest as well. At $500 each, they aren't cheap, but considering that I'll pay bike fees to United Airlines ($400 roundtrip to Paris) plus $150 to Air France (for a two hour hop from Copenhagen back to Paris), I'd end up $50 ahead if I choose to use Airport Ninja. Hmmm....
