Between CA, FM, and MU, you'll presumably have many options to choose from. Off the top of my head:
LHR, LGW, MAN, CDG, AMS, FRA, MUC, BER, MXP, FCO, VCE, BRU, MAD, BCN, ZRH, VIE, IST, ATH, and BUD. This massive array of flights (most of which overfly Russia --> cheaper to operate) is one of the main reasons non-Chinese airlines have been struggling to operate in the black...and the key to easily reaccommodating all displaced passengers.
