I have a CDG_PVG DH block time 1130. Trip is published for First class. TIcketed for business class on China AIrlines and the ticket is about 2/3 of the First class fare shown in the pairing.

I know the contract says block over 10 they must book in the following order First -discounted, business- full fare or discounted, and first- full fare.

Any techniques on how to get ticketed or placed in First, as depicted on the trip summary?

I've heard anedcotally that biz on China Air is far inferior to US Flag carriers biz class. COntract also states that we'll us US Flag carriers or foreign equivalent)
