The pay thing (comparing BA and so forth) I can't verify. Maybe he can prove it. I'd hazard a guess that he is using only the A380 pay, but don't BA pilots all get PAID the same thing ei. their A320 drivers make the same rate as an A380 driver? Something about "pay points" springs to mind.
No, BA pilots do not all get paid the same! Years ago that was the case, but now there is a different rate for shorthaul (B737/A320 family) / medium haul (B76) and longhaul (B747, B77, B787, A380). At the top of the paypoints a SH Captain's basic pay is about 85% of a LH captain's. Their pensionable pay is the same however, to discourage people jumping to LH just for a pension hike.
Note that a 747 captain earns the same as an A380 captain!
SH pilots are flying about 770 hours per year, longhaul about 870 hours - to draw a comparison between wage rates, you would need to take this into consideration!
