Haven't written in a while because I've been flying around with the Brompton in tow! What a joy to have a great bike with me to jump on an go. But I've a bit of experience now with traveling with the Brompton. I have to admit, as I'm packing it up and hauling it around ( I used to just travel with carry ons ), I sometimes wonder if it's worth it. But as soon as I jump on the bike - great stuff!

I used the B&W black hard case and it's already been bent fairly badly. I have the extended seat tube and on one trip, I left in the downtube but had it stick out the bottom a bit so that it fit. A mistake - at some point, they handled the luggage so roughly that the seat post rammed up against the interior of the case and bent some of the frame. It could be a case of where if they *know* it's a bicycle in a soft case, they'll treat it better. Still I think I rather just go with my hard case as a precaution.
