So my first flights on OW await me, and with a slight change in travel patterns, it seems possible there will be more... Maybe I should get some card then. Mainly I am deciding between QR and AB at the moment, as these two are the ones that I have the next flights with.

Questions

(1) What is most important to you in a FFP?
(upgrades on travel, priority services when flying the airline, extra baggage allowance, good award redemption rates, better award access, free - discounted lounge access, etc.)
Reply:
Ideal would be lounge access at departure airports at Silver, but I don't think anyone has that anymore, then lounge access at hub airport (free and/or paid in both cases), good award rates, last good award ticket rates (if practical at all due to fees and relatively low mileage

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
(<25000, 25000-50000, >50000 miles - <25, 25-50, >50 flights?)
Reply:
20-40k status miles, 15-20 sectors, mostly longhaul

(3) What types of fares do you usually buy?
(First, Business, Premium economy, Economy, cheapest)
Reply:
Economy exclusively, mix of fare classes depending on chance, from discount to full fare. Mostly middle of the road buckets

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Reply:
Can choose within reason (depending on price difference, must have a reason for more expensive tickets e.g. to avoid too long trip duration).
Travel almost exclusively for work (pleasure travel almost exclusively on LCCs)

(5) Which routes and airlines do you fly most often?
(US Domestic, Transpacific, Kangaroo, in Asia etc)
Reply:
Expecting a number of Europe - Asia trips.
Formerly I would fly almost exclusively LH longhaul to Africa and Asia, but schedule changes and destination composition changes forced me to change my patterns. LH used to be most convenient.

(6) What is your home airport?
(SFO, SCL, London LHR, HKG, Singapore SIN etc.)
Reply:
KSC, BUD.

(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?
(AA Executive Platinum, QF Gold, UA 1K, LAN Comodoro, etc)
Reply:
Some miles in M&M, not significant amount. No status.

I'm mostly considering QR, as coming QR trip is going to be relatively high fare bucket, and there is a bigger chance to use more QR flights for future Asia travel.
Alternatively I'm considering AB, as they are relatively close by European airline, have some useable Topdeal Ticket promos (I can travel to VIE for private travel relatively easily) and I think I saw here I could get a silver card from them for 4 months for free, which could come in handy during next trip with AB (jan/feb)
