LAS-bound flights are the slower direction by about 35 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.
| Great-circle distance | 2,432 km · 1,511 mi · 1,313 nmi |
|---|---|
| Initial heading | 263° (W) from ORD; 66° (ENE) from LAS |
| Farthest from the equator | 42.0°N |
| Crosses | neither the equator nor the 180th meridian |
| Share of the longest possible trip | 12% of the 20,015 km to the far side of the Earth |
| ORD | America/Chicago — UTC−5 now; UTC−6 standard time, UTC−5 during daylight saving time |

| Difference | Las Vegas is 2 hours behind Chicago today. |
Jet lag, flying ORD → LAS. Your body clock has to move 2 hours later, like a westward trip. A shift this small rarely causes much jet lag; most people feel normal within a day or so. Flying the other way, the shift is reversed.
