The problem is that the scraps might be a little too much, and a little too rare, for the little fish in the pond. A lot of 6-day trips as too big to add to your schedule outright, and the 3-days that might actually fit are snapped up before the junior pilots can get them, assuming they're not (still) too big also.

Looks like a very comfortable living if you're not greedy, and you like London, though.
