Taking your bike on the plane? American Airlines recommends that a passenger pack a bike in a rugged bicycle carton, for sale at its ticket counters for $10, or from a bike store. Further, they suggest that all detachable accessories be removed and packed separately and handlebars be turned sideways. The carton should be filled with packing material to prevent shifting in transit and sealed with strong tape. Previous labels should be removed and the carton marked with instructions such as ``THIS END UP,'' with a shipping label showing owner's name and destination address.
