(1) What is your home airport? KBP - 75%, LWO - 25%
(2) What types of fares do you usually buy? Economy, discounted economy, seldom economy-priced deal for business
(3) How many miles do you usually fly each year? 70-100k in actual miles, >50 segments, earn >40k TK miles/year
(4) Do you have any kind of status at present? What is it? TK*G, PS Premium (issued for 1 year only if one flies 20+ segments - I do), W6 WizzClub
(5) What is most important to you in a FFP? 1) Lounge access (pref with 1 guest on the same itinerary), 2) Upgrades, 3) Priority in case of delays/cancellations, 4) Companion tickets
(6) Which routes do you fly most often? Ukraine-EU and intra-EU, much less Ukraine-Turkey, intra-Ukraine, 2-4 long haul flights a year (N America, SE Asia) with additional few local flights there, seldom Caucasus and Central Asia
(7) Preferred Airlines? TK, but my European routes and schedules mostly get me on LO, PS and LH. I avoid OS (bad scheduling in VIE if you have to cross Shengen border and poor miles earnings on TK). Used to do up to 10 RT flights a year on W6, but they cut Ukraine, so I will abandon them.
(8) Do you travel for work or pleasure? Short/medium haul mostly work (more flexibility, mid-priced), but long haul for leisure (fixed dates, cheaper fares)

I was actually thinking if I should:
(1) stay with TK and aim for Elite+ and thus have 4 years to start over with a different program or continue with TK
(2) move to a more generous (?) UA
(3) move to Asiana to get their lifelong *A*G
(4) switch to LO/LH as I fly them most, try to earn *G status there
