I bring my on the plane with me in two heavy carry-on wheeled cases. One case also carries my computer and therefore qualifies me for them both being free (one carry on and one personal, such as laptop computer case.

The important tbhing with doing it this was is a direct flight. The last thing you want is to schlep two heavy cases around an layover airport.

As for other supplies and misc items I ship them out ahead of time to friendly fellow chip collecting buddies who have homes /condos in Las Vegas and are kind enough to accept them for me. They then deliver them to the show for me.
