A meeting point is only fair if both drivers know what they are signing up for. Here is the context at each end of the 1105.7 mi drive.

Bismarck keeps Central time and Henderson keeps Pacific — a 2-hour difference. Drive times are clock-agnostic, but wall clocks are not: leave Bismarck at 9:00 am and, after the 17 h 17 estimated drive, it is about 12:17 am the following day in Henderson. Clock-change weeks can shift this by an hour.

Driving between Bismarck and Henderson costs an estimated 17 h 17 behind the wheel. The great-circle distance is only 1043.1 mi; at a 460 mph cruise with 90 minutes of airport overhead folded in, flying works out to roughly 3 h 46 gate-to-gate — an estimate, not a schedule. Airport transfers, security, and boarding eat some of that edge, so the honest comparison is 17 h 17 of driving versus about 3 h 46 from curb to curb when the connections behave.
