Benchmark Airport's 6,000 ft of runway puts it in the longest quarter of Montana's 62 jet-capable fields, and at 5,434 ft the field is high enough that density altitude takes a real bite out of what that runway will accept on a warm afternoon. 16 of the 24 types we broker clear it; the runway rules out 8. The nearest city we publish corridors for is Bozeman, 143 miles away.

Access

Getting here

Straight-line distances from the cities we publish, with a typical aircraft's block time including taxi, climb and descent.

From-prices are one way and all-in — operator price, our fee and federal excise tax — for the smallest cabin suited to the distance, indicative rather than quoted. Short legs sit at the smallest cabin's daily minimum, so we show distance and time for those and price them on request.

Runway

What can operate here

Compared against the published balanced field length of every type we broker, with roughly 3% added per 1,000 ft of elevation for density altitude.

This is runway length only. Individual airports also restrict by wingspan, noise curfew, slot availability and special approach certification, and performance moves with temperature, weight and the day. Clearing the runway here means an aircraft is worth asking about — the operator confirms it, and signs for it.
