Hi -- I'm seeing conflicting information on this.

If I'm flying HEL-LAX in business class on an AA-issued, Finnair-operated ticket as a Oneworld Emerald, will I be able to use the business lounge and platinum wing?

I've seen some information that says it has to be AY marketed for status lounge benefits to apply, and others say you get into business class lounge based on class of service flown. This confusingly might mean that I get access to business lounge but not platinum wing (which requires status access).

I have never seen this scenario before. Anyone who could confirm what will happen is greatly appreciated.
