1) Read this article regarding flying with your bicycle: http://www.ibike.org/encouragement/travel/bagregs.htm

2) Go to your airline and look up their baggage policy with regard to bicycles.

3) If you have a place to put your hardshell case when you arrive, rent one from your LBS. If you don't have a place to store a case when you get there, use a cardboard box. I recommend the Madone.
