With the New Series the rear triangle and the front fork can easily be removed so that the entire bicycle can fit into the largest size suitcase the airlines will accept as standard baggage. I've only traveled once with my double pylon and the airline allowed me up to two standard size bags free (flight to Europe from North America) so I put some parts into each bag instead of trying to cram it all into one suitcase which worked very well. It is quite a bit more work to break it down than a Friday so I wouldn't recommend it if you are traveling a lot, but for the occasional trip you can avoid the excess baggage charges. Of course, if you can afford a double pylon then you can probably afford the baggage charge.
