John Murtha Johnstown/Cambria County to Lancaster Airport JST → LNS
117 nautical miles (135 statute miles) east on a straight line, true course 095°, about 105° magnetic at the departure end (variation 10W). At 120 knots that is 42 min at the quickest height in today's winds (34,000 ft, a 47-knot tailwind), arriving about 9:31 pm EDT (01:31 UTC), after sunset at the destination. Right now JST is low IFR, wind from the northeast (050°) at 6 knots; LNS is marginal VFR, wind from the east (080°) at 9 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: 1 flights in the DOT's last twelve reported months, the route's page.

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.
