I'm not sure if I am coming from left field or approaching this in too much of a logical, not to mention, reasonable position...

But does the answer to your problem not just lie in coming to some arrangement with the other Pilot?

I mean, saying you can't be stuffed is fairly, well, ignorant and so is his stance of saying you must tell him before flying...

Would a simple... You fly on ABC days of the week, or phone call, not save a lot of time, hassle and money?

Sorry if this is not the same as the other answers but... "Yes" it is worth being reasonable, both parties, and coming to an amicable arrangement...

Cheers

P.S. If you try, or have tried to do this already, and he won't... just Shoot him down... [8D]
