Hi guys!
I will be moving to MKE from Germany. Currently I am a *S with LH. I am not really a frequent flyer, but would like to, if possible, achieve *G somehow, mainly for lounge access.

My main traveling will, most likely, be 3-4 TATL from MKE via YYZ to ZRH in nonflex eco, as AC seems to be the only carrier that allows me to connect to international flights in the evening, after work (there is a 7:20PM flight to YYZ, from where I could connect to the last LHR flight of the day).
Apart from that I will fly domestic occasionally.

I just realized that AC increased the threshold for *G to 50000mls, which might be doable in a year with 4 TATLs, but difficult if I only do 3. Are there any good alternatives? I am a bit relucatant regarding A3, as I would like to redeem the miles at a certain point. TK only credits 70% for AC Y.
