Having completed a round-the-world trip across 3 continents, 8 countries and 19 cities, and getting ready to hop around Latin America for a couple of months, I've learned a few "best practices" to make the planning phase smoother and less of a pull-your-hair-out experience.
If you're flying 15 to 18 hours, you really should try to get some sleep. Decide if you want to sleep when your body decides it's time or if you're going to try and get on the time schedule of your destination.
The fact is that the everyday-ness of today's airports is exactly the opposite of what we flyers need. Don't wall us off, you builders, from where we are and what we are about to do. We may be frightened but we are not dumb.
The airplane flights that do the grunt work of your trip, that allow you to get from place to place, are a sort of forgettable magic that, if you are like me, you do not record in your diary or photograph.
