I love taking last-minute trips, and the Southwest Airline Low Fare Calendar has been perfect for that. I don’t always have a fixed destination, so I just check the calendar, see when the cheapest dates are, and go. Last month, I ended up booking a quick trip to Nashville because I found a super low fare that fit perfectly with my free weekend. It really takes the guesswork out of last-minute planning. The best part is how quick and simple it is to use. Has anyone else here used it to score spontaneous getaways, or do you think it works better for planning in advance?
