Denver International to Mahlon Sweet Field DEN → EUG

864 nautical miles (994 statute miles) northwest on a straight line, true course 293°, about 285° magnetic at the departure end (variation 8E). At 120 knots that is 7 h 12 min at the quickest height in today's winds (8,500 ft, no wind along the track), arriving about 12:44 am PDT (07:44 UTC), after sunset at the destination. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 2,522 flights in the DOT's last twelve reported months, the route's page.

Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
