Guessing they're not counting stuff at their flight sim training center (12 bays) as a 'data center'. There is zero % chance that the workloads supporting simulators are gonna run in the cloud. They're incredibly latency sensitive, extremely finicky, and just getting the stuff virtualized continues to be a struggle for aviation OEMs and flight training centers (though FedEx was a pioneer in this regard).

Granted, the footprint per sim bay isn't huge (1-2 racks, usually, sometimes 3), but it can add up at the larger sim facilities. Several of the major airlines are running 30+ bays simultaneously, with United poised to come in with the most at 40+ in the near future.
