I've had 2 flights between LHR and GVA canceled as of this morning; my sense is that the various governments are over-reacting to this new variant, however that doesn't change the fact that this sort of thing can quickly snowball, and my sense is that it may be in the process of doing so.

I didn't want to post this into the existing threads on Covid and Dec. flight cancelations, as those are bogged down with other issues such as BA Holiday rebookings, award ticket rebookings, etc.
