you can also pay about $50 extra on most airlines to take a piece of cargo, but you also have to give up one bag. but, the budget traveler thing to do here is go down to the bike shop and get one of those boxes that they get their new bikes in, they'll usually give you one, then pack your clothes and anything else that will fit in the same box. this also pads your bike a little. then you get to claim it right then and there when the plane lands, no waiting while your bike does a solo world tour on some cargo ship.
