Just booked an AS codeshare flight HNL-HND rt on HA metal in biz.
I'm a longtime Pualani Plat now matched to MVP 75K/oneworld Emerald.

I can't figure out if there is any benefit to crediting the flight to Mileage Plan vs. HAMiles?
I'm gonna get 150% EQM in either program.
I'm gonna get 100% elite bonus miles in either program.
Plumeria and Sakura lounge access are included. I don't think I would get access to the JL First Lounge at HND as a oneworld Emerald since it's a HA flight.

So my impression is that everything is equal so my plan is to credit the flight to HAMiles for the silly benefit that most FAs on the Japan flights take meal orders based on elite status.
Anyone have an opinion or experience to help me figure out if there is a benefit to crediting my flight to AS or HA?

Mahalo!
