Hi

When I read your thread title I thought you were in a tight spot / sticky situation! Looks like it's an innocuous FFP question.... *whew*
From what I can read, you have miles in three programs: QF, SQ and TG.
First things first: mileage expiry. For QF of course it's no expiry provided there is no continuous period of 18 months with no activity. For SQ and TG, it's three years rolling and strict, i.e. if you earn miles in 2010, you have until (usually the end of) 2013 to redeem those miles, otherwise they expire from your account. And if you earn miles in 2011, you have until 2014 to redeem those miles, and so on. When you redeem an award, the oldest miles are used first.
To answer your main question, if I had to choose between SQ and TG, I'd pick SQ. On first glance the SQ FFP looks more attractive than TG, plus you can usually get a credit card that can build up SQ miles (e.g. dedicated rewards card, or Amex MR can convert to KrisFlyer miles at 1:1 ratio). SQ also often have promotions related to award flights, including a seemingly non-terminating "promotion" of 15% less miles if you book online.
The only things that SQ awards are notorious for are:
- On all aircraft except for 747s and 333s, J and F awards must be redeemed at the Standard and/or Full level, not Saver level. Suites on the 388s can only be redeemed by calling the SQ call centre, and they cost an absolute fortune. Still, mileage levels are comparable with other FFPs even at Standard levels, and doesn't really affect you if you redeem plenty of Y anyway.
- Fuel surcharges are reportedly higher than some other FFPs (except the obvious USA based ones).
Be aware that if you fly on Economy sales fares (i.e. really cheap Economy), some of these fares will only earn points on the operating FFP and not other alliance FFPs. Some may then only earn partial credits rather than full. And some do not earn at all. For example, SQ's "Sweet Deals" fares (Economy sales) book into fare class code N. These do not earn any miles at all on any Star Alliance FFP or even SQ's KrisFlyer.
A better question to ask yourself is who do you fly more often (besides QF). In most (but not all) cases and depending on your flying patterns and objectives (e.g. status, earning and burning miles (and if so, how often would you expect to do this every year)), you're best to join the FFP of the airline you fly the most. There are some exceptions, especially in *A since there are so many programs and airlines, but at the beginning the same question is asked: what are you flying patterns.
I have no experience with booking awards with TG or SQ. Never heard many people around that are with the TG program; more hear people that are on the SQ program. Most people don't appear to have trouble getting award availability on SQ, even in premium classes.
