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.
STOP!!!
Do not go with AC. Do not go with A3. Go with MP.
Nonflex eco means Tango. With AC and A3, Tango credits only 50%. Yes, I repeat 50%. You will never reach 50K miles. Not even A3's 20K.
Stick with MP. MP credits 100% for AC Tango flights.
