Do you travel light or heavy?
I put a lot of thought into taking as little as possible so I wash clothes most nights. Unfortunately that's a bit offset by the need to take all sorts of electronic stuff for my work.
Cattle or first class?
Depends what the airlines offer. Mostly economy, though on my latest trip to Europe, Emirates flew me business class which was wonderful, and we paid for my wife to fly business class as well. At our age we need a bit of comfort on very long flights.
What type of suitcase do you carry?
