Flight to Montana Crazy Price Jump

Just wanted to vent that I had been eyeing a flight to Great Falls which was in the $300s and jumped to +$900. This is for a flight nearly 4-5 months away. Was waiting on confirmation from the rest of my party if they could do the trip - the second everyone greenlit, the price skyrocketed lol.

Man, flights to Montana are expensive - just venting and praying it goes back down.
