This article is from the Bicycles FAQ, by Mike Iglesias with numerous contributions by others.

I checked the FAQ for information about taking bikes on common carriers
and riding in and out of airports some time ago.
At that time there was little information so I initiated a mini survey on
these subject on rec.bicycles.rides, etc.
Now I have collected information on cycling in and out of about 100
airports around the world and using trains in the US and Europe.
This information is at http://www.GFonline.ORG/BikeAccess. Although the web
may have eclipsed the FAQ for certain purposes, it might still be possible
to provide a pointer to this data, almost all of which was contributed by
readers of r.b.r (who's email addresses appear in the listings).
