You have to pack it in an FAA certified shipping crate - they are hard plastic and run around $200-300. You can get them from any online bike shop. Some LBS have them for rent as well. I believe there is also a fee that varies by airline... others will have more info on this.
The last time I took my bike on a trip I sent it UPS and it got severely abused. I would recommend FedEx if you opt not to fly with it. Whenever I have looked into flying with the bike it has worked about to be the same price as shipping (that's within USA).
