Houston to Bryce Canyon National Park

We flagged this Houston to Salt Lake City fare at $218 just over a week ago, and it has dropped another 44% to $121, slipping below even the cheapest we'd ever tracked on this route. Normally this one runs close to $490, so $121 on a one-stop Frontier itinerary is a rare dip worth locking in for a quick ski trip or city break. Because it's priced below the historical floor, it could be a short-lived fare glitch, so treat it as a bonus if it holds.
