It looks rather empty, not sure if that's a good or bad thing based on current production rates.
I count 24 new built aircraft. 15 of those are KC-46's and that in itself does not sound good
Looks like a push to get frames delivered before Christmas cleared the flightline. Also, some frames are in paint. Usually there are 4-6 787's on the flightline in Everett, with an equal number or more in Charleston. Everett turns the deliveries quickly, nothing like Airbus, where you see frames parked everywhere. Charleston runs a bit slower, but has been getting faster over the years.
If you want to see photos of a full flightline, go to the Woody Aeroimages blog for the Renton plant. Usually there are dozens of 737's there.
