Hailstone: I've heard that flights would resume yesterday 12Sep 1700Z. Today it was (apparently) Candian airspace closed. Cut it short, it's Thu 2240LT central Europe (2040Z), Wednesday's freighter aren't going anywhere.
Lets face it: -F operations (especially non-US) are very low down on the pecking order.
I'd guess:-
1)US Govt/military/relief flights
2)Depositioning diverted aircraft
3)US domestic
4)Limited international pax (mainly delayed fights)
5)International pax
6)Fedex/UPS
7)Delayed intl cargo
9)Anything else I've forgotten
10) Anything else my neighbour has forgotten
11)Perhaps scheduled freight.
Early next week is my personal opinion.
