I’m located in Europe and need some help deciding between BA, AA and AS.
The last 4 years, I have had BA Silver (OW Sapphire) or Gold (OW Emerald) status from flying cheap QR business class tickets to Asia and cheap BA/AA/IB/AY business class tickets to the US.
But I have recently flown more on miles, so for this year I haven’t renewed my BA status yet.

I have three bookings in Finnair I class to CAN/HKG from Germany.
Something like TXL-HEL-HKG and back.
Apart from that, I don’t have any longhaul travel booked yet for this year.

I’m wondering whether I should credit those flights to AS, BA or AA.
AS would yield the highest number of the most valuable miles - but they’re not a Oneworld member yet and a devaluation is incoming.
BA wouldn’t yield as many miles, but it would help with renewing my status.
AA has the challenge to Platinum Pro (I’m a Hyatt Globalist).

I have very few domestic flights in the US, so lounge access in the US or upgrades on domestic AA flights aren’t very important to me.
I could also credit the AY flights to AS and then book something with QR, purely to renew my BA status. But then again, I’m wondering how much sense that makes... Status actually isn’t THAT important to me. It’s just nice to be able to select seats for free (especially on BA metal - but then again, I try avoid flying BA...).
And the other benefit that I use is lounge access, especially at MAD. And of course fast track security.
I only fly business class on longhaul flights though, so again, it’s not that critical.
But I do fly IB in economy from time to time, etc.

Most of my economy class flights are with Star Alliance nowadays, and I’m already covered there.
But I still think it would be nice to keep Oneworld status as well.

So... What would you do?
