Since starting PD in Aug, I have travelled domstically twice in the US with my PD Home Choice Pro cycler. It fit nicely in a Pelican 1610 case (with foam to minimize movement), and the case seems sturdy enough to be checked. It will not fit in the cabin, either overhead or closet. It's too large and heavy (45-50 lbs total).

TSA locks did not matter. The first time I checked it in, I installed 2 TSA-approved locks. They were broken off on the outbound. I added 2 more for the return, and they were broken off as well. For my second trip, I left the case unlocked and the machine was fine.

I've also used United's Baggage collection service and it worked out well. UA picked up the checked luggage and delivered it to my hotel within 2 hrs of my checkin.

The solution bags were shipped by Baxter to the designated hotel, and they need a minimum of 2 weeks notice for domestic 48-state travel. I called the hotel prior to arrival to alert them about the shipment from Baxter that needs to be held for me. All other ancillary PD supplies were packed separately and checked in.

Next month will be my first int'l trip, this time with manual PD. So no machine (and voltage/power issues) to worry about.
