Found a "solution" to fly on this product whilst earning actual PE accrual MQMs/MQDs. Booked through AF on an AF-coded ticket (AF "A" fare) on KL metal in their PE/Premium Comfort cabin. Looking forward to trying this product. I'm already certain the seats will be way more comfortable than those awful shell zero-head-recline seats AF currently imposes on the LAX-CDG route.

I just wish if KL PE/Premium Comfort fares earn proper DL MQMs/MQDs the DL website and KL chart would just say it. If someone reports here they earned PE DL mileage as opposed to Economy while flying KL-coded PE product, I'd feel comfortable booking with KL.
