Eurowings Discover has had YYC-FRA loaded as 12x weekly since September, there's been no schedule changes made. Its basically the 5x weekly they previously served plus the daily service they took over from AC.
WS had strong loads on both LGW/LHR this past summer, so its kind of surprising LGW got out right dropped instead of say reduced.
As for WS, they requested slots for LIS in S24:

Presently the slots were denied.
ATH/LIS would be good additions from YYC as neither have much service from Western North America similar to FCO/BCN/EDI.
I've heard rumblings about at least one new route coming, but I'll keep it at that until the information becomes public.
