HAS anyone in the world traveled as widely in recent years as Secretary of State Hillary Rodham Clinton and the aides who accompany her? Philippe Reines, her chief spokesman and “the deputy assistant secretary for Doing Hillary’s Bidding,” as The Washington Post once called him, logged 111 countries with Mrs. Clinton in four years (the one country he missed was Hungary) before she was grounded with a health scare.

In travel terms, he’s “hard pressed to think of another job that’s comparable” to Mrs. Clinton’s, he said, noting that even commercial pilots have consistent routes and guaranteed breaks. In contrast, in a single trip over 12 days last summer, Mrs. Clinton and her team flew to France to Afghanistan to Japan to Mongolia to Vietnam to Laos to Cambodia to Egypt to Israel. Below are edited excerpts from a conversation with Mr. Reines on what travelers can learn from the nation’s top diplomatic team.

Q. How do you keep your bearings on a trip like the one you described?

A. No one could keep track of the time. During the Arab Spring, they had made a decision in Egypt about daylight saving time, and the Air Force computer didn’t know it. So you’ve got a planeful of people Googling the time. She had a meeting with the president, and we couldn’t figure out if we were on time or an hour late.

Q. Any packing tips?

A. The key to packing is to never unpack. Clothes aside, I don’t take anything out of my bags. I have a toiletry bag that is a mirror image of my bathroom at home. I am incredibly heat intolerant, so I don’t wear a coat. I spend as much time on Amazon trying to miniaturize commonly used travel items as some rogue nations do trying to miniaturize warheads.
