Today is a great day to book a flight if you need to! Southwest is having a sale.
Remember, even if you already booked a flight, check to make sure they are not cheaper today. If they are, you can change the flight to the cheaper flight and they will save your credit for an entire year so you will save money off a future flight.
I had flights already booked for later this year and was able to get a $49 credit!!!
Go here to check on prices.
