Travel is stressful, no doubt. But the stress of travel can be minimized with some planning. For example, use a checklist to make sure you pack your toiletries. Print out all your travel related information and keep it in a folder. Dress in such a way that streamlines your way through security.

As for the wife and dog, I'm of no help. :) It sounds as though your travel is work-related, though, so maybe there's some added stress by association.
