I've taken my BOB to Europe and made a small chloroplast box for it. The restrictions on total weight one can take when flying bikes differs with each airline and if you exceed these weights one can get tagged whopping big charges. I had the bike in a box, BOB trailer in a box, plus one large bag for the gear and it cost me only $100 in 2000 by Air Canada. I had them placed as luggage on same flight I went on.
There is also the possibility if travelling only in US ship by train or by US ground mail and hold for pickup, I've heard some cyclists have tried this at a cost saving.They sometimes handle it better than airlines do.
I hope this helps you.
