No OP! You are not alone to me, actually in good company. If you must travel with collegues then you seemingly are "always-on". Rare do I find a collegue that Id actually want to fly with. If anyone has read Men are from Mars Women are from Venus.....well..... Travelling alone is my man cave. Window seat, iPod, bose headsets, food as they say leave me the heck alone except for exceptional FAs service. Plus I too have my own travel preferences, in hotels, how I get to/from the airport, lounges, showers, the luggage I bring, where n when to get food or how I regulate my jet lag etc.
