I think I need to choose a new FF program and want some help from those in the know. A little history first.

I am, by my own admission, really bad at choosing an airline loyalty program. I started in 2005 with VS and got Gold for two years running by the skin of my teeth and by some questionable routing. In 2008 I joined BD because they status-matched me to BD*G, but hardly any of my journeys were on BD metal so I never got op-ups. The *A network kept me in Gold on that until BA bought BD. I refuse to fly on BA (a long story, not worth getting into) so I got comp status matches to TK and NZ. I used the NZ card for the last year but missed retaining Gold by 10 points and never flew on NZ metal the whole year. I now have BA Gold, TK*G and NZ*S in my wallet. By far, most of my flights are on LH, although I do travel all around the world mainly on *A airlines.

Question is, what do I do now? NZ only seems to earn points on around half the *A flights I take and TK seems to be a poor earner, so both of those don't really interest me. Most of my flights seem to be on LH, but it seems like it's hard to get to SEN status and most SEN's seem to be constantly complaining about M&M's devaluation. I'd like to stay with *A as they have the best worldwide coverage.

Any suggestions ?
