Dupage Airport to Harry Reid International DPA → LAS
1,297 nautical miles (1,493 statute miles) west on a straight line, true course 263°, about 264° magnetic at the departure end (variation 1W). At 120 knots that is 13 h 31 min at the quickest height in today's winds (8,500 ft, a 24-knot headwind), arriving about 6:47 pm PDT (01:47 UTC), after sunset at the destination. Right now DPA is VFR, wind from the south-southeast (160°) at 4 knots; LAS 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.

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.

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 DPA.

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 12 forecast points nearest it (JOT, DBQ, BRL, DSM, OMA, GRI, GLD, DEN, PUB, GJT, BCE, LAS). A plus sign is a headwind, a minus sign a tailwind.

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.
