Not a peak cargo question, but this is probably as good a place to ask as any:
Why does KFSD (Sioux Falls, SD) seem to punch so far above its weight in terms of cargo flights?
This is the list of FDX & UPS arrivals from Friday:
FDX 1543 A306 MEM
UPS 492 763 SDF
UPS 670 752 SDF
UPS 2576 763 SDF
FDX 795 A306 MEM
UPS 2572 752 SDF
UPS 491 763 YYC
Last week there were also flights to LGB and DSM among other places.
This is respectable stuff, including five heavies, for a city whose metro population (MSA) is only ~270k. That's substantially smaller than Madison, WI, for comparison. And FSD is not that far from MSP and OMA, much bigger cities.
Is FSD some sort of regional mini-hub, filling a similar function as Cedar Rapids CID?
Or is it bank traffic? I know Citi, Wells Fargo, and some other banks have major operations there.
Something else? Amazon super warehouse in the area?
Couple different angles to the answer here.
FSD might not be that large of a metro, but it's the biggest city in quite a large area, and obviously the economic center of the state. UPS and FedEx have feeders that cover the state from the FSD ramp - for instance, FX flies freight from Aberdeen, Pierre and Rapid City to feed Sioux Falls flights. It's not too far of a straight-line distance from, say, MSP, but too far to feasibly flow express airfreight through MSP. So I'm not surprised the volume is there. If Billings and Fargo can fill up widebodies once a day, FSD certainly can. Which brings me to my next point.
BIL and FAR are a bit out of the way between population centers - unless you're SEA- or MSP-bound - so you'll only see those metros getting the basic number of flights. FSD on the other hand is in a great location for tag-on transit flights. You'll see flight routings like ONT-FSD-RST, ONT-FSD-GYY, SDF-FSD-BIL, RFD-FSD-GEG. Obviously I'm making up these pairings but it's a simple illustration. If FSD rates half an A300, and BIL rates half an A300, combine the freight and give the flight two stops. You see this a lot among smaller markets with the integrators. And this is what FSD is seeing, partially.
