My wife and I try to tour overseas every year and got tired of the hassle of full size boxed bicycles. It is no fun having to push two boxed bikes for endless blocks in Tokyo. Now we have two folders from Gaerlan.com (http://tinyurl.com/odml). Last January we rode part of the Vietnam coast (http://tinyurl.com/odq2) We got to Saigon and after two days flew with the bicycles in their regular size suitcases to Hue, the beginning of our tour. We mail the empty suitcases from Hue to Saigon's main Post Office (Poste Restante) for about $2.00 each. Completed the tour and got the suitcases at Saigon's Main Post Office, no problem. I think you can do this in most countries, even within the US (ie, Seattle to San Diego)

In our case the rack fits inside the suitcase with the bicycle. We don't carry much stuff when overseas. Most of the time motels and hostels are very cheap thus all our stuff fits in an expandable trunk bag, a handlebar bag and a medium-large size camelback type backpack. We take the handlebar and backpacks with us in the plane and place the trunk bags in a very light weight duffel bag that has some extra space for any purchases we made. We like this set up, and for now, don't think would go back to boxed bikes.
