September and October are consistently the cheapest months for ORD–LAS. January (post-New Year's) is also surprisingly affordable. Avoid major Vegas events — Formula 1 Grand Prix (November), New Year's Eve, and long weekends.
Tuesday, Wednesday, and Thursday offer the lowest fares. Weekend departures — especially Friday evenings — are the most expensive by a significant margin.
The ideal booking window for Chicago–Las Vegas is 4–8 weeks ahead. Vegas is a spontaneous destination, so last-minute inventory exists, but prices spike 0–7 days out as leisure travelers fill seats.
Midway Airport (MDW) is often 15–20% cheaper than O'Hare (ORD) on this route, particularly on Southwest. Always search both.
Camli's expert agents can sometimes bundle consolidator airfare with hotel packages. Call 1-855-919-6470 for package pricing on Vegas trips.
Both ultra-low-cost carriers run ORD–LAS flash sales multiple times per year. Camli's deals page surfaces these automatically.
If you're flying out Friday, consider returning Tuesday instead of Sunday — you'll save $40–80 on the return leg and miss the Sunday airport chaos.
