Cisco Systems lands in Billings, Montana after a week of Texas-to-Montana shuttles

Cisco Systems flew from Billings, Montana, to Gregory, South Dakota, on the evening of May 31, arriving just after 5 p.m. local time at Gregory M. Simmons Memorial Airport (KGZN), a rural field with no scheduled commercial service. The 2-hour-9-minute leg in the Bombardier Global 6000 (tail N600NB) capped a busy week for the aircraft: five flights in the previous two days alone, all between Cisco’s Richardson, Texas, base (roughly 33°N, 99°W) and the Billings area.

No major conference, product launch, or public appearance is documented in Gregory or nearby southern South Dakota this week, per a scan of local event listings and news reports. The simpler explanation is that the flight likely ended a multi-day trip, returning the aircraft and its passengers to Cisco’s West Texas hub — the same region the plane visited repeatedly between May 26 and May 31, all tracked from Richardson. Cisco Systems’ proxy allows executive personal use of the fleet with reimbursement for incremental costs, but no public records connect this specific routing to a named event.

For a company that shuttles executives between San Jose, Richardson, and Raleigh-Durham routinely, the May 31 leg appears to be a repositioning flight back to Cisco’s Texas operating base after a weekend in Montana — a quiet end to a busy holiday-weekend travel pattern.
