Nashville International to Ontario International BNA → ONT

1,518 nautical miles (1,747 statute miles) west on a straight line, true course 274°, about 277° magnetic at the departure end (variation 3W). At 120 knots that is 13 h 56 min at the quickest height in today's winds (4,500 ft, a 11-knot headwind), arriving about 7:30 am PDT (14:30 UTC). Right now BNA is VFR, wind variable at 3 knots; ONT is VFR, wind from the west-southwest (240°) at 9 knots, gusting to 16. 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: 669 flights in the DOT's last twelve reported months, the route's page.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 UTC · at 120 knots true airspeed

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 14 forecast points nearest it (BNA, CGI, SGF, FSM, TUL, OKC, GAG, AMA, TCC, ABQ, FMN, PRC, BLH, ONT). A plus sign is a headwind, a minus sign a tailwind.

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.
