Too often. We're going in February and I've been checking about every other day. The rates have been going all over the place. Allegiant, a newer option in the Lansing, MI area, hasn't posted its February rates. With NWA being our other only real option, it's tough to do anything. If they go into bankruptcy, I'm sure schedules/prices will change again. Prices are too high right now for our trip. Hoping they come down so I can book and stop this madness.
