Which oneworld programme to choose?
 

I have a trip coming on AY.

IST-HEL-BKK-HEL-IST. on R class. Just paid 362eur for it. Including everything. ;)

I do not travel on oneworld airlines normally so I am not a member of the any of the oneworld FFPs.

Not sure if I ever fly with them but just in case, which FFP do you recommend to join?

Thanks!

Curiously, neither AsiaMiles nor BA nor Qantas list R on AY as earning anything at all, whereas AA lists it as full fare economy earning 100% + 1.5EQM

Then again on Finnair itself R seems to earn 50%

So if that isn't a mistake on the AA website (or you're prepared to fight to hold them to it) then clearly the answer is to go with AAdvantage.

(Note in passing - I have just discovered that CX deep discount classes (NOQS) earn 50% on Finnair Plus too; looks like I might be getting me one of those then)
