Allegiant Air flies nonstop to Las Vegas from more than 50 small and mid-size cities across the US. It's the airline's home base and biggest operation, with Harry Reid International Airport (LAS) serving as headquarters. Fares start low, often under $50 one-way, and the all-nonstop model means zero connections.
Bellingham International Airport (BLI)
Bellingham connects Pacific Northwest travelers to Las Vegas in about 3 hours. Allegiant is the primary carrier at this airport, keeping fares competitive. Flights run a few times per week.
Des Moines International Airport (DSM)
Midwest travelers from Des Moines can reach Las Vegas in roughly 3 hours 30 minutes. It's one of Allegiant's busiest routes from Iowa, with multiple weekly departures.
General Wayne A. Downing Peoria International Airport (PIA)
Central Illinois passengers skip the drive to Chicago with this nonstop route. Flight time is around 3 hours 45 minutes, with service running a few times weekly.
South Bend International Airport (SBN)
Northern Indiana and southwest Michigan residents get nonstop Las Vegas access. Flights take about 4 hours, running 2 to 3 times per week.
The Eastern Iowa Airport (CID)
Cedar Rapids travelers fly nonstop in around 3 hours 30 minutes. Popular for weekend getaways, with service a few days each week.
Lehigh Valley International Airport (ABE)
Allentown gives East Coast travelers a nonstop connection to Vegas. Flight time is close to 5 hours, serving eastern Pennsylvania and western New Jersey.
Cheapest Months to Travel
September, October, and January offer the lowest fares. These months fall outside peak holiday travel, so Allegiant drops prices noticeably. One-way tickets under $40 are common on many routes during these windows.
Peak Travel Seasons to Avoid
Prices climb around Thanksgiving, Christmas, New Year's Eve, and major events like CES in January. Summer weekends and spring break periods also push fares higher.
Best Time to Book
Allegiant fares work best when booked 4 to 8 weeks out. The airline doesn't fly daily on most routes, so seats disappear faster than you'd think. Adding bags at booking also locks in the lowest luggage fees.
Midweek Advantage
Tuesday and Wednesday departures nearly always cost less than Friday or Sunday flights. Weekend demand runs higher on Allegiant's leisure routes, so midweek travel can save $20 to $40 per person each way.
Time Difference to Keep in Mind
Las Vegas runs on Pacific Time (PT). That's 3 hours behind New York, 2 behind Chicago, 1 behind Denver. If you're coming from the Midwest or East Coast, your body clock will be ahead, which works in your favor for late-night plans.
