JAL Mileage Bank - Upcoming Itin - Q on 767s

Have a trip next summer on JL, with the following itinerary, all in business class.

ORD-NRT JL9
NRT-PEK JL789
PVG-NRT JL622
NRT-LAX JL62

Does anyone know which configuration of 767s normally fly the PEK and PVG routes?

I know that JL9 usually has the 747 config with the extended business class and no biz on the upper deck (L04)...and that JL62 is usually (L17) and will choose those seats accordingly.

Looking forward to JL business. My last 2 trans-pac trips were on AA in their business class, so this should be a nice upgrade. Haven't flown JL except for a short NRT-ITM leg, for years...last time was JFK-NRT back when it was still Executive Class and 2-4-2 on the 747s, so a long time ago.

JL789 NRT=PEK: A41 Configuration
JL622 PVG=NRT: Likewise

Thanks.

Have booked 17AC on the trans-Pacific legs (the seat map for JL9 showed J on the upper deck, which I wasn't expecting)

Avoided the bulkhead row on the 767 flights.
