St. Pete-Clearwater International to Niagara Falls International PIE → IAG
930 nautical miles (1,071 statute miles) north on a straight line, true course 010°, about 015° magnetic at the departure end (variation 5W). At 120 knots that is 6 h 50 min at the quickest height in today's winds (34,000 ft, a 16-knot tailwind), arriving about 8:35 am EDT (12:35 UTC). Right now PIE is VFR, wind calm; IAG is IFR, wind calm. 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: 234 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 9 forecast points nearest it (PIE, JAX, SAV, CAE, GSP, ROA, EKN, AGC, 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.
