And on top of that I'll have my computer backpack containing one laptop and my briefcase with the other computer. (The second computer controls the sound effects for the game, assuming we actually have someone to operate it.)
Normally I've not minded checking my CPAP machine inside my luggage, but the weight is likely to be a problem. I'm considering taking the risk of carrying the CPAP along as a second personal bag and hoping that Alaska won't balk at me. I know TSA will allow the machine through -- it's just that Alaska's web site is vague on the subject.
