Observed Fare Range: ORD to LAS Price Data from Travelpayouts
greenspicks pulled Travelpayouts fares on June 17, 2026 and observed one-way prices ranging from $93 to $175 across multiple July 2026 dates from ORD to LAS. These are individual cached fare observations, not a comprehensive fare calendar or airline ranking.
The fare spread reflects real tradeoffs. That $93 Frontier fare on July 13 comes with 516 minutes of total travel time, meaning a lengthy connection somewhere en route. Compare that to a $100 Frontier nonstop on July 28, which clocks in at 248 minutes. The $7 difference buys you back nearly four and a half hours.
Mid-July dates showed higher pricing in the data pull. A July 12 departure on Frontier was $175 for a nonstop at 248 minutes. Meanwhile, July 4 showed a $117 nonstop option, and July 1 came in at $118. Both of those Independence Day weekend fares had 256-minute flight times.
The lowest observed fare ($93) required 516 minutes of travel time with a connection. The cheapest observed nonstop was $100, saving 268 minutes for just $7 more.
August dates in the ORD data showed mixed results. An August 4 American nonstop was $112 at 238 minutes. August 25 on Frontier dropped to $105, but with a connection stretching the trip to 941 minutes. Alaska appeared in late August at $126 (August 19, 483 minutes with one stop) and in early September at $122 (September 2, 483 minutes with one stop).
These observations represent individual data points from a single retrieval, not a guaranteed pricing pattern. Fares shift based on demand, booking timing, and seat availability.

How to Find Budget Flights from Chicago to Las Vegas: Step-by-Step
These steps reflect the booking approach greenspicks uses when researching route-level fare data.
- 1
Search both ORD and MDW
Chicago has two major airports serving Las Vegas. In this data pull, the cheapest nonstop was from MDW ($99), while the lowest overall fare was from ORD ($93 with a connection). Neither airport is universally cheaper.
- 2
Use flexible date calendars
Fare search tools with calendar views show price variations across nearby dates. A one-day shift moved fares from $175 (July 12) to $93 (July 13) in this data pull, though the cheaper fare had a connection. See the greenspicks flexible date flight search guide for technique details.
- 3
Set fare alerts for your target price
Rather than checking daily, let a flight price tracker tool notify you when fares drop. Set alerts for both Chicago airports if you can depart from either.

Evaluate the connection tradeoff
The $93 fare from ORD on July 13 had 516 minutes total travel time. The $100 nonstop on July 28 took 248 minutes. That $7 saved you from a connection that added nearly 4.5 hours. Decide if your time is worth more than the fare difference.
- 5
Book when the price meets your threshold
There is no universal “best time to book” for this route. The greenspicks guide on best time to book flights covers general patterns, but route-specific fare alerts remain more reliable than calendar rules.
