Wow, thanks, that's some really helpful info. Sounds like it shouldn't be too much trouble to get the British licenses
Good info that I need to start tracking which flights were done under IFR too.
I'm not sure exactly where in London I'll wind up living, but work will be near Paddington. From my research so far, it seems like Biggin Hill and Denham are the easiest airports to access via trains and public transit (I likely won't have a car), but any other suggestions are more than welcome!
