Southwest Extends Schedule Till January 2022
Southwest Airlines releases their schedule in chunks, unlike the more traditional airlines at close to a year out. It can be frustrating at times but when schedules open up it is worth checking for deals. You can now book Southwest flights through April 24, 2022. That means you get about 7 months worth of window to plan! You can check their flight schedules here.
It appears the flights are a little pricey, at least from my few checks. If you have Rapid Rewards points it may be worth booking anyway and locking the prices in. With Rapid Rewards you can easily rebook if the price drops and recoup your points so no reason not to book if you have them in your account. Then periodically check the flight to see if prices drop.
Check out the extended schedule and see if you can find any good deals. Holiday flights are always expensive so it is best to get them locked in early and see how it plays out.
