"I have an OAG and I know how to use it."
But most travellers haven't a clue what an OAG is, much less how to use it....

One strategem which helped me last year was arranging a little extra time on business travel in order to be able to take advantage of bumping opportunities. Especially given that I'm single, it's not much hardship to spend a couple of extra hours in the destination city and be able to see the sights a bit.
