PFO
Surely you'll be looking at the RHS before the LHS?
However, interesting question. I'd also love to know how the airlines view their pilots doing other work on the side (like IT contracting or financial advising), as I'd be very interested in doing my current job (but as a contractor) on some of the days that I'm not flying (in years to come, if I ever make it to the RHS of any TP or jet)
