Charlotte/Douglas International to Buffalo Niagara International CLT → BUF
475 nautical miles (547 statute miles) north on a straight line, true course 012°, about 019° magnetic at the departure end (variation 7W). At 120 knots that is 3 h 58 min at the quickest height in today's winds (39,000 ft, no wind along the track), arriving about 2:38 am EDT (06:38 UTC), after sunset at the destination. Right now CLT is VFR, wind from the southwest (230°) at 8 knots; BUF is VFR, wind from the east-northeast (060°) at 6 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: 2,298 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 02:00–09:00 UTC · at 120 knots true airspeed
The eastbound cruising heights for this course (VFR: odd 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 (GSP, ROA, EKN, AGC, PSB, BUF). A plus sign is a headwind, a minus sign a tailwind.

Based on data from the 12th at 00:00 UTC; valid on the 12th at 06:00 UTC for use 02:00 to 09:00 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.
