(1) What is your home airport? BOS as of now
(2) What types of fares do you usually buy? Tend to fly W (premium economy) on trans-atlantic flights, sometimes J if there is good promo, Y to South America (US government fares)
(3) How many miles do you usually fly each year? >120k
(4) Do you have any kind of status at present? What is it? Flying Blue Platinum (in fact, lifetime but not official yet); AAdvantage Platinum
(5) What is most important to you in a FFP? Upgrades, lounge access, access to reasonable seats
(6) Which routes do you fly most often: US>Europe and US>South America
(7) Preferred Airlines: Sometimes I can't chose if it's a travel for work and there is a US gov contracted carrier, otherwise AF, KL, SU, BA or AA.
(8) Do you travel for work or pleasure? Mostly for work

I would like to get a status in *A with the lounge access, availability to upgrade with Miles on UA and with an easy way to re-qualify if I have to occasionally fly UA on gov fares. Will consider switching to LH/LX/TK for flights to Europe. Now I can match my AF status to TK Gold. But the Asiana lifetime Gold for 500k sounds very attractive. I would like to balance between *A and OW to have premium status on both of them without flying too much. Any suggestions?
