I assessed that with my flying patterns status with OW is out of reach. But let me cross check here.

(1) What is your home airport?
Reply: CPH, WAW
(2) How many miles do you usually fly each year & in what class? (<25K, 25k-50k, >50k)
Reply: economy, about 100 segments intra Europe a year + 3-4 long hauls a year
(3) What types of fares do you usually buy ? ( First, Business, Economy etc.)
Reply: low economy
(4) Can you choose your airlines and/or, class of service?. Do you travel for work and/or pleasure?
Reply: I travel for work, but most on my personal expense. I can choose airlines. So far I see no better way than to fly at least 50-60 segments in Europe with *A, based on my locations. But the rest I can consider reallocating (and this 50-60 segments gives me *G).
(5) Which routes do you fly most often (US Domestic, Transpacific, Kangaroo, in Asia etc)
Reply: intra Europe.
(6) Do you have FFP status of any kind of OW or other airline at present? What is it?
Reply: I am only *G and have access to Diners Club lounges.
(7) 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: lounge access > priority > upgrades matter. The rest does not matter for me at all.
(8) Preferred Airlines: from CPH/WAW I can use AY, BA, AB. On long-hauls to US I can use AA perhaps 1-2 times a year.
