(1) ZRH
(2) Mostly economy
(3) 25k-30k (but maybe 40k next year)
(4) nope
(5) Good award redemption rates, upgrades and extra baggage (10kg is sufficient)
(6) Intra-European plus 1 or 2 inter-continental trips per year
(7) lx, (tk)
(8) Mixture of both (for work, it's mostly lx.)

At first, I was considering A3, but I actually don't really need lounge access, as I have a DC cc and basic priority pass, and don't really care for priority boarding. I also have a cc that collects some M&M miles, but I don't think I will be able to collect any substantial amounts with it (around 10k per year). Mostly looking for a program with good redemption rates, high award availability and with low additional taxes.

Cheers and thanks in advance for any help!
