Buffalo Niagara International to Nashville International BUF → BNA
550 nautical miles (633 statute miles) southwest on a straight line, true course 225°, about 236° magnetic at the departure end (variation 11W). At 120 knots that is 4 h 18 min at the quickest height in today's winds (12,500 ft, a 8-knot tailwind), arriving about 11:55 pm CDT (04:55 UTC), after sunset at the destination. Right now BUF is VFR, wind from the east-northeast (070°) at 3 knots; BNA is VFR, wind variable at 3 knots. 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: 747 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 6 forecast points nearest it (BUF, CLE, CMH, CVG, LOU, BNA). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 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.
