Los Angeles to Denver
$46$34086% off
Round trip
Frontier just dropped Ontario to Denver to $46 round trip nonstop, which is even below the $53 all-time low we have tracked on this route across hundreds of price checks, so it could be a short-lived mistake fare. Denver in late summer and early fall means easy mountain day trips and cooler evenings before the fall crowds arrive, so it is worth grabbing while it is live.
