It's the duration given by a reputable travel search engine for the end-to-end trip, from when the first plane takes off until when the last plane lands, including transit time, etc., and a fixed buffer for getting to the airport, etc. Still not really accurate, but it helps factor in indirect routing and the like. The shortest available current routing is chosen; that routing may not actually be available during the meeting, etc. Cheers, -- Mark Nottingham http://www.mnot.net/
