You better at least tip the van driver

The good cities have rentals. Plan on $20-$60 depending on what and how long. I could do quite a few rentals for what my setup cost. Another good option, but over multiple years and a possible Uber there and back, it adds up.

Keep a couple of things in mind. You’re going to have to gate check it at times when you have unscheduled deadheads ect.. If you are scheduled to DH on a partner airline they are probably going to require you check it to baggage claim. That might delay your outbound flight.
If you are a selected for additional screening at KCM will the bike be allowed through normal screening? If not some TSA Officer is going to appreciate his new bike!

My folder fit though xray..

Gate checking has never been a problem.. even when DH on mainline... I think people don't realize how small the folding bikes are, especially the Friday packit. Ive gate checked my regular bag and the folder in the dash or 145 closet many times. No one even knew.

If you are using the b&w case for the Brompton, expect it to get trashed fairly quickly. None of the folders are anywhere near as good as a full-size bike. I have carried on my Brompton using the slip cover that folds up under the seat, but only on flights where I know there is no overhead bin. Other than the checked-luggage size pelican style cases for them, I do not think there is a way either of the bikes will survive being gate checked.

vs the Ticket: ticket packs lighter, if you have the carry the Brompton for long the 25 lbs gets old real fast. The Brompton is faster at folding and can roll on the rack wheels while folded. Brompton front luggage option is pretty super. Integrated pump means you have one less bit of clutter with your other stuff.

vs S&S bike: much longer to put together, but you have a real bike, that's possibly lighter than the folders, and if you have to put it into checked size luggage anyways....S&S case is 26x26x10 - which is roughly the same size as a Brompton case.

vs other options: rentals, raphia clubs, bike shares, or even stashing a few cheapish, but good bikes at repeat locations means a whole lot less to lug around and be in everyone's way.

For all of them: don't forget you probably want to bring helmet, tools, tubes/patch kit,

I find myself taking swim goggles and running shoes more than my Brompton - and I hate running. But the Brompton is really good for public transit and getting the "last mile" around my domicile.

USMC translation:

“Overnights start in the bar. You want to leave the bar? Knock yourself out.”

I’m with you!!

I somehow feel this will be short lived....your standard CRJ overnight isn’t 18 hrs in some paradise where zipping around on your bike will be possible....instead you’ll be arriving into some place like Des Moines IA or Jackson MS for 12 hrs at around 10 or 11pm after a long day. You might get single overnights where you can use it, but I suspect the cost/benefit analysis of lugging it around for those few times will quickly be realized. Happy pedaling

Yeah, this sounds like a major PITA, he he! Just take up jogging and use the hotel bike or rent a good one when you have a nice overnight with time to peddle.

No. Just no. Leave the bike at home.
