I will be moving to SIN soon.
In parallel with nice perspectives about living there, there are some unclear thoughts like "what to do with FFP, SQ, BAEC, BA Amex, BD DC and other FT-related things?"
I am sure there are many people previously based in the UK but moved to SIN. Would be very thankful for your advise and thoughts on the best options.

In my new SIN role, I will be flying:
- 1-2 times/month to South Asian countries in Y (shorthaul flights) or J
- monthly to China on in Y or J
- quarterly J to Europe (most likely on BA dueto corp deal) or Americas
Hope above info might help you to give more detailed advise on what FFP programme/strategy I should choose and follow.
Therefore the questions are:

1) Should I switch all mileage earning to SQ KrisFlyer or better to continue earning to BMI DC (I am Gold and have 120k mile sitting there)?

2) How easy is it to spend BMI DC miles on SQ flights (I wonder how "mileage seat inventory" is allocated between members of SQ and other *A programmes)?

3) What will happen with my BA UK-based account/mileage (I have 400k in the books)?
If I move my BAEC account to SIN address - what is the process, prons and cons?

4) What to do with BA Amex credit card? UK-based "BA Amex" card offers one of the most generous benefits - annual voucher allowing to take a companion on miles-paid flights (the seat availability is scarce to use this benefit on some popular routes incl SIN, but the principle is place and I value this benefit very highly - all my longhaul BA leasure travel is in business class thanks to this Amex programme).
Is there similar SQ-AMEX partnership/programme in SIN and how to join it?

Many thanks in advance for all your thoughts, hints and tips!

What an exciting time! I discovered FT 3 years ago, found lots of good advise that did change my travel life (horray to BAEC board^ ) and now I have to start once again with SQ and SIN! Hope I will be a regular visitor and contributor to this board
