(1) What is your home airport? PEN
(2) What types of fares do you usually buy ? H
(3) How many miles do you usually fly each year? 35K, this year possibly up to 60K
(4) Do you have any kind of status at present? What is it? M&M Silver
(5) What is most important to you in a FFP?
I have 100K+ miles on M&M and plan to use them for 2 special-offer-return-tickets FRA SIN for relatives of mine.
Personally, I would like to get to a point where I can do at least one-way upgrade SIN-SFO or SIN-FRA once a year. Also important is luggage allowance.
(6) Which routes do you fly most often? Transpacific, Asia, Asia-Europe
(7) Preferred Airlines? only SQ
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?) work, I stay home for pleasure

Remark: What annoys me is that M&M silver is extremely useless with SQ (no 125% miles, zero miles on PEN SIN, no extra luggage allowance, no lounges in SIN, no early boarding, etc.). So now I thought of leaving the 100K+ miles in the M&M and start over new in Krisflyer.
Trade-off seems to be that Kris has lower silver status miles (and therefore earlier 125%), but awards are a lot more expensive than M&M.

So, should I stay or should I go?
