The carriers do already have practice ramping up and down for Christmas and Chinese New Year so it seems plausible they could absorb significant extra volume in whatever time it would take to negotiate the leases on the extra flights they use during those times.
For that matter customs processing also has experience managing the same surges.
I'd believe we might have some sort of own-goal planned for customs that could hang things up.
