5. Why stand up? Because I've been through at least three - usually five - seemingly interminable queues and hours of sausage-machine-style processing just in order to get to an under-sized seat into which I've been shoe-horned for too long (especially if the flight's more than about 90 minutes) and I can't wait to stand up.
As a minimum hours PPL, I used to enjoy being up in the air but the modern commercial flying experience seems somehow to suck any remaining joy out of it. I just want to get on and off as quickly as possible and get on with my day.
What's more, four times out of five I travel with just hand luggage, and I know what time the train home is, so getting out of the tin tube as quickly as possible means I get to the front of the immigration queue and on my way quickly. It just helps improve my day.
Fair enough?
