Thanks for any advice - just running out of patience with United after being hit hard this year with changes in eligibility rules: status down from Platinum to Silver as significant flights on partners weren't counted.

(1) What is your home airport? (SFO, LAX, MCO, etc.) LHR
(2) What types of fares do you usually buy ? (C, F, Y, etc.) Varies - last year included Q, V, T, K
(3) How many miles do you usually fly each year? (<25K, 25k-50k, >50k) >50K (often 100K+)
(4) Do you have any kind of status at present? What is it? (UA Premier, M&M Senator etc) UA Silver about to start - UA Platinum running out this month
(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.) Upgrades would be nice - but probably not realistic flying economy; Lounges vital; Priority useful too
(6) Which routes do you fly most often (US Domestic, Transpacific etc) Intercontinental - last year included UK-USA/Addis Ababa/Australia/Singapore/Johannesburg
(7) Preferred Airlines: Turkish works quite well now they've improved security at Istanbul, but planes themselves not always great. Quite liked United for the Economy Plus seats with power, but service with them really dropped last year.
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?) Work - but always focused on cheapest (or close to it) fares

Thanks for your help.
