Oakland San Francisco Bay Airport to Laurence G Hanscom Field OAK → BED

2,321 nautical miles (2,671 statute miles) northeast on a straight line, true course 066°, about 052° magnetic at the departure end (variation 14E). At 120 knots that is 14 h 04 min at the quickest height in today's winds (39,000 ft, a 45-knot tailwind), arriving about 9:28 pm EDT (01:28 UTC), after sunset at the destination. Right now OAK is VFR, wind from the east (100°) at 5 knots; BED is IFR, wind from the north (360°) at 5 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 flights in the DOT's last twelve reported months, the route's page.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 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.
