Charleston Afb/Intl Airport to Boeing Fld/King County International CHS → BFI

2,095 nautical miles (2,411 statute miles) northwest on a straight line, true course 307°, about 314° magnetic at the departure end (variation 7W). At 120 knots that is 17 h 36 min at the quickest height in today's winds (4,500 ft, a 1-knot headwind), arriving about 10:08 am PDT (17:08 UTC). Right now CHS is VFR, wind from the west-southwest (250°) at 7 knots; BFI is VFR, wind variable at 4 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.
