MCI-MSP is my route and both Delta and Southwest are going higher on the route than usual, especially for 4th of July, usually I can book in advance for $200 or less. I will say that Memorial Day has been much cheaper than I expected. Fortunately, I've been amassing a ton of points but the prices for Fourth of July are just crazy currently, almost $300. I'm hoping prices go down for Thanksgiving and Christmas when the schedule extension comes out in a couple weeks.
