I have a 2005 downtube VIII- I really like it - I use it to commute when I don't need full hybrid and it fits better into my office. I have never travelled by plane with it - but others have - it is a little more complicated than just simply folding =but I think it is supposed to fit into a regular large suitcase. If you are interested in a folding bike - I suggest reading the forums at bikeforum.net (I think- it may be bikeforums.net) - there is a section devoted to folders.
