Los Angeles to Denver
$157$34054% off
Round trip
Frontier has nonstop Ontario to Denver fares at $157, down from the roughly $454 this route typically runs, a 65% discount that makes a Rocky Mountain trip an easy yes. Dates are open through the fall and into ski season, so this works for October hiking or December first tracks. Nonstop service out of ONT makes the getaway even easier.
