Globetrotter,
You are quite right. I recall the flight was shared with MME.
This was, however, a) in pre AF/KLM days, and b) in better economic circumstances.
I don't know what the loads or yields were like, but Gill Air, of course, folded. And no one rushed in to fill the gap in the marketplace.
The world has moved on since then, and now that AF & KLM are one and the same organisation I can see no appetite on their part in 'robbing Peter to pay Paul'. They're probably quite happy with things as they are.
