Hi, I would appreciate your insights on which FF I should choose going forward ... TIA

I'm currently BAEC Silver. But, I will lose this soon as I havent been travelling during pandemic and travel post-pandemic has been limited.

(1) What is most important to you in a FFP?
Reply: upgrades (though I hardly get them), seat selection, priority boarding and extra baggage would be nice, I rarely redeem award tickets (usually redeem miles to upgrade to business seats), lounge access would be good (but I could give up since I have Amex lounge access too)

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
Reply: <25000 miles in economy and <25 flights

(3) What types of fares do you usually buy?
Reply: cheapest, but have also done the QR business tickets in the past for quick Tier Points

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Reply: yes can choose airlines but usually in economy class. Current travel is only pleasure.

(5) Which routes and airlines do you fly most often?
Reply: I used to live in UK and made frequent trips to US and Asia. But I have now relocated to Asia and planning to make frequent trips to New Zealand and some US (no more UK/Europe trips).

(6) What is your home airport?
Reply: SIN

(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
Reply: AA (no status, miles used to upgrade AA segments), BAEC Silver (most miles are banked here), Qantas (no status, just started pre-pandemic)

(8) Preferred Airlines? Most common Airlines flown on?
Used to fly BA (unlikely in future), AA, QR (only for tier point runs), CX and QF
