Monterey Regional to Harry Reid International MRY → LAS
325 nautical miles (374 statute miles) east on a straight line, true course 093°, about 078° magnetic at the departure end (variation 15E). At 120 knots that is 2 h 08 min at the quickest height in today's winds (39,000 ft, a 32-knot tailwind), arriving about 8:49 pm PDT (03:49 UTC), after sunset at the destination. Right now MRY is marginal VFR, wind from the southwest (220°) at 11 knots; LAS is VFR, wind from the south (190°) at 12 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: 219 flights in the DOT's last twelve reported months, the route's page.

Green, blue, red and purple airport dots are the flying conditions reported there now (VFR, marginal VFR, IFR, low IFR); grey means no report. Red areas are SIGMETs, orange areas AIRMETs, hatched red areas temporary flight restrictions. Map tiles: OpenFreeMap, data © OpenStreetMap contributors.
Warnings the route crosses SIGMETs and AIRMETs whose area the line passes through or comes within 25 nm of
- AIRMET TANGO 1W: moderate turbulence above 18,000 ft from 18,000 ft to 39,000 ft. Near the route, at the departure end.
- AIRMET TANGO 3W: moderate turbulence below 18,000 ft (due to mountain wave) up to 15,000 ft. Over the route from 158 to 197 nm out.
- AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft. Over the route from 207 to 295 nm out.
- AIRMET ZULU 3C: moderate icing up to 22,000 ft. Over the last 79 nm of the route.
- AIRMET TANGO 4W: moderate turbulence below 18,000 ft up to 18,000 ft. Over the last 20 nm of the route.
A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from MRY.
Pilot reports along the route within 50 nm of the line, last three hours, the serious ones first
- C680 descending, 0 nm north, 5:46 pm PDT (00:46 UTC): a broken layer from 3,000 ft to 3,500 ft. At the departure end, 0 nm north of the line.

Winds aloft along the route, and the time en route the forecast for use 20:00–03:00 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 3 forecast points nearest it (FAT, BIH, LAS). 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.
