Lakeland Linder International to March Arb Airport LAL → RIV

1,840 nautical miles (2,117 statute miles) west on a straight line, true course 290°, about 296° magnetic at the departure end (variation 6W). At 120 knots that is 15 h 44 min at the quickest height in today's winds (4,500 ft, a 3-knot headwind), arriving about 8:31 am PDT (15:31 UTC). Right now LAL is VFR, wind calm; RIV is VFR, wind from the south-southeast (160°) at 10 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.

The westbound cruising heights for this course (VFR: even thousands plus 500 ft; above 18,000 ft the forecast levels), with the wind averaged along the line from the 18 forecast points nearest it (PIE, TLH, MOB, MSY, LCH, SHV, CLL, DAL, ABI, LBB, INK, ROW, ELP, ABQ, TUS, PHX, BLH, ONT). A plus sign is a headwind, a minus sign a tailwind.

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.
