Hello,

I currently have TK silver after being downgraded after a status match. I'm heading to Australia for Christmas and am struggling to get a good deal on OW, but *A is throwing up some good fares. At the moment I'm looking at the routing below in J:
Lufthansa: Milan > Frankfurt > Seoul
Asiana: Seoul > Syndey
ANA: Sydney > Tokyo
Swiss: Tokyo > Zurich > Milan

Where am I best to credit to to get as close as possible to *A Gold?

(1) What is your home airport? (SFO, LAX, MCO, etc.) LHR
(2) What types of fares do you usually buy ? (C, F, Y, etc.) Y short haul and J when a good deal is on long haul
(3) How many miles do you usually fly each year? (<25K, 25k-50k, >50k) <25k at the moment
(4) Do you have any kind of status at present? What is it? (UA Silver, M&M Senator etc) BA silver - expiring March '20
(5) What is most important to you in a FFP? (Frequent upgrades on travel, priority services when flying the airline, good award redemption rates, free lounge access, etc.) Lounge access
(6) Which routes do you fly most often (US Domestic, Transpacific etc) Europe short haul and 1 or 2 long haul which could be anywhere
(7) Preferred Airlines On *A, not bothered
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?) Just leisure now
