I have a few flights with JAC booked to KUM. JAC (Japan Air Commuter) is a a subsidiary of JAL and I know for sure that JAC credits to JAL Mileage Bank (JMB) same as JAL flights.

I normally credit my JAL flights to BA Exec as TP/Avios. I am hoping I will get some TP (for whatever it is worth) for the JAC KUM flights.

Does anyone know for sure? Just curious. A google search says "yes" but I'd thought I'd ask.

EDIT. I often book JAL flights from my Expedia account where my Expedia account is linked directly to BA Exec, and all my JAL flights booked that way always got me TP, Avios and my BA Status has always been reflected on my JAL boarding passes booked this way.
