If I keep seeing the physical connection to City A flapping, of course bgp will flap, but will I be able to use route dampening to control the instability
No. BGP flap dampening only works on routes that go up and down periodically while the BGP session they're learned over stays up. When the session goes down the dampening info is removed.

But it doesn't matter: you're screwed both ways. If you keep routing stable you lose packets, if you import the flapping into your routing protocols those become unstable. You need stable links.
