Boise Air Trml/Gowen Field to Tucson International BOI → TUS
731 nautical miles (841 statute miles) south on a straight line, true course 158°, about 145° magnetic at the departure end (variation 13E). At 120 knots that is 6 h 58 min at the quickest height in today's winds (7,500 ft, a 15-knot headwind), arriving about 11:35 am MST (18:35 UTC). 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: 5 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). 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.
