I've seen that you can use Google Flights to find smoking deals on last minute flights when the destination and dates are flexible. For example I just entered "1 week trip in October, leaving from Des Moines." I'm seeing options for Orlando, Phoenix, Vegas, Miami, Ft. Lauderdale, Portland, Austin, Nashville and NYC for less than $130 per adult. You can go to Denver for $55 if you're willing to fly Frontier. You can go to San Diego for $177 from 9/28 - 10/2. And most of the time these are prices directly from the airline, and it links you to the airline's booking site to purchase. That’s handy when you want to upgrade, flights get canceled, etc.My wife and I are looking to get away for a long weekend in the middle of October and are trying to come up with ideas. I’m looking for any recommendations on places for a 3-4 day weekend trip (within the US) that you’ve been on and enjoyed.
