Route Overview: Chicago to Las Vegas
Linking the Midwest's largest hub to the country's premier entertainment destination, the Chicago (CHI) to Las Vegas (LAS) route is driven almost entirely by leisure demand, with bachelor and bachelorette parties, conventions, concerts, and casino getaways filling seats year-round. United and American both maintain strong presences out of Chicago, while Southwest's significant Las Vegas operation adds heavy competition that keeps fares more volatile than on typical business routes. Spanning approximately 1,520 miles, the flight takes an average of 3 hours and 25 minutes, and because demand is so closely tied to weekends and events, fare swings on this route can be sharper than on routes with steadier business travel.

- Departure Airport: Chicago O'Hare International Airport (ORD) or Chicago Midway International Airport (MDW)

Tips for Inexpensive Flights from Chicago to Las Vegas
Learn the secrets of how to get cheap flights to Las Vegas and have an enjoyable journey while saving money.
- Always compare: The massive Midwest presence of Southwest causes healthy competition among airlines for this route that does not really exist elsewhere in O'Hare.
- Choose mid-week flights: This route has such a high level of leisure traffic that its entire pricing structure depends upon the weekend getaway phenomenon.
- Buy 5 to 8 weeks ahead: With all the trade shows, sporting events, and concerts in Las Vegas year-round, demand can increase even on normal weekends.
- Count on low-cost carriers: Spirit Airlines and Frontier both operate this route and offer the lowest prices, which help keep the fares of legacy airlines low.
- Look for the event calendar: Holiday weekends like Memorial Day, July 4th, and Labor Day coincide with increased tourist numbers, so fares hit the roof, other than CES and New Year's.
Consideration of Seasonality in Price
The prices for this route depend mostly on the abundance of conventions in Las Vegas, the weekend demand, and the seasonal temperature in the desert southwest. This kind of route differs from business travel in that the prices are dependent not on the days of the week but on top of the weekly pattern of weekend price increases.
January
A steep increase in prices can be noted in the first two weeks because of the CES – one of the biggest international exhibitions that fills up hotels and planes in advance. Prices return to normal levels after the exhibition finishes.
February - April
Prices are relatively stable due to comfortable weather and numerous conventions, such as those associated with March Madness.
May - August
Despite the hot temperatures in the desert, these months are one of the most expensive periods. It is connected to pool season in Las Vegas, summer holidays, and numerous conventions.
September - October
Prices will drop significantly as summer vacation travel slows down; however, there will be some brief price increases due to big conventions and concert series starting on certain weekends, despite the general downward trend.
November
It is the cheapest time of the year, especially in the two to three weeks preceding Thanksgiving, during which the level of conventions and weekend leisure travel reaches its lowest point before Christmas travel demands begin to rise again.
December
Prices will go up during the month and peak on New Year’s Eve, one of the most expensive times of the year for travel as the city holds big celebrations and events at resorts.
