Round trip
STL to Las Vegas is going for $234 on Frontier right now, down from a typical fare that usually runs closer to $470, a 50% drop. It's one stop each way, and this looks tied to a wider Frontier sale we're tracking this week, so grab a date that works for a winter desert getaway while the fare holds.
