I only know Albert's side of the story, so I can't offer a balanced view. Albert says the reason he and the cellmate can never fly anywhere on the same plane or even the same day, is because of their divergent strategies for planning and packing.
For the cellmate, the best way to spend the weeks before travel is:
(1) Go out every night with a different friend. By the time you get on the plane, you feel exhausted but completely connected to everyone in your life. Actually, written down like that it looks quite sensible really! A downside is that you end up doing your packing at the last minute, and forget half of what you need.
(2) Decide shortly before the trip that you need to redecorate and refurnish the whole house. Call in a designer, and make a load of impulsive and expensive decisions at a time when you're both already overstressed at work and at home.
Albert himself prefers the normal travel preparation strategies:
(1) Start packing a month beforehand.
(2) Cut off from other people, spend the last few weeks working on lists and elaborate systems. By the time you get on the plane, you feel completely alone and completely in control of everything. Actually, written down like that it doesn't look quite normal after all.
