I am now using Miles and More from LH and CSA OK Plus. I think LH has pretty hard elite status conditions and pretty bad earnings.

(1) What is your home airport?
VIE, BTS
(2) What types of fares do you usually buy ?
cheapest available
(3) How many miles do you usually fly each year?
25-45k
(4) Do you have any kind of status at present?
None
(5) What is most important to you in a FFP?
Good mile earnings and redemptions (for this OK Plus is much better than M&M). Possible upgrades.
(6) Which routes do you fly most often? European Union
(7) Preferred Airlines
None
(8) Do you travel for work or pleasure? (Can you chooose your airlines, class of service?)
Half work, half pleasure, but for work I buy my tickets and can choose everything.

I am starting to think, that LH M&M is not the best option for me. OK+ has worse availability and VIE is mainly *A domain anyway.
