Hi,
I have never had a jet lag, although I know how stressful air traveling can become from personal experience.
A lot of people believe that traveling by air is only fun. However, if you ask frequent air travelers, and especially business travelers, you may be surprised to know that they stop enjoying it after a point. It's like commuting by car or train.
I believe the element of adventure and the unknown is what makes a journey interesting, problems aside.
