Lower deck lavatory: A340-600. I have been fortunate to travel in many parts of the world since the age of nine. Although trains remains my favorite mode of ground transportation—especially in Europe where I grew up and during a day’s ride you can see the panoramic landscape transform in front of your eyes—taking an airplane is a must when speedy travel overseas is essential, of course, if you have time, a slower voyage across the Atlantic with the Queen Mary 2 is memorable.
