Next, you need to click on the cheapest fare date that works best for you. You’ll then be redirected to a list of available SWA flights low fare calendar results for that chosen day. From here, you just need to pick your preferred time, fare type, and review the details.

Tips to find the cheapest fares on Southwest

If you want to get a deal on Southwest Airlines, then you’ve got to come up with the right strategies; otherwise, be ready to pay hefty prices. But why pay more when you can fly for less and still enjoy the perks, right? We’ve put together some smart hacks to use the Southwest Airlines low fare calendar and book the cheapest flights possible.

  • Be flexible with travel dates: When you’re booking flights, flexibility is the key to getting the lowest fares. Try to get midweek or off-peak season flights as they often come with better deals. You can do that by adjusting your dates slightly and enjoying the perks of lower fares. 
  • Book in advance: Use the South west low calendar to book your flight in advance to get lower airfares. Many airlines release tickets several months prior to the departure date, and Southwest is the same. As the departure date gets closer, prices increase, but if you plan ahead, you can even benefit from early-bird discounts.
  • Set fare alerts: When you set fare alerts on Google Flights or Southwest’s app or website, you’re notified when there’s a drop in airfares for your desired route. What this does is it allows you to keep track of fare fluctuations and book when prices are at their cheapest.
  • Use the low fare calendar frequently: You won’t get the real deal on Southwest flight prices by checking once. You'll have to revisit the Southwest fare calendar a few times while planning. The more you monitor it, the better your chances of catching flash deals or last-minute drops will be. 
  • Travel during shoulder seasons: Try to fly during shoulder seasons, spring or fall, considered the best times to book Southwest flights for cheaper fares. These off-peak times have less demand, so the prices drop often. And when you combine them with the Southwest low airfare calendar, you’re almost guaranteed a bargain.
  • Consider nearby airports: If you can change your departure or arrival airport, you might find lower prices. Say you’re flying out of Oakland instead of San Francisco, or Dallas Love Field instead of DFW, then you’re likely to find better rates of the low fare calendar Southwest Airlines offers.
