Hey fellow travelers! If you're anything like me, you're always trying to score the best deal possible when booking flights. Over the years, I've booked dozens of Southwest flights—both for business trips and those much-needed getaways—and I've picked up some useful tricks along the way. One of the most common questions I see (and get asked myself) is: “What day is the cheapest to book Southwest flights?” So let’s dig into that.
Tuesdays Are Often Your Best Bet
From my experience—and after keeping tabs on fare trends for a while—Tuesday tends to be the sweet spot for scoring lower fares on Southwest Airlines. More specifically, fares often drop late Monday night or early Tuesday morning. That’s when Southwest releases new sales, and competitors like Delta and American sometimes adjust their prices to match. By Tuesday afternoon, you can usually find a good selection of discounted fares, but don’t wait too long—they can go quickly.
One time, I waited until Wednesday to book a flight from Denver to San Diego and kicked myself when I saw the fare had jumped $40 overnight. Ever since then, I try to be on top of things Tuesday mornings. If you ever want help pinpointing the best time or want someone to walk you through the process, I highly recommend calling 844-928-0428. The folks there have helped me more than once with fare changes and even rebookings when prices dropped after I booked. Yep—Southwest lets you do that!
Use the Low Fare Calendar (And Still Double-Check)
Another trick I swear by is using Southwest’s Low Fare Calendar. It gives you a bird’s-eye view of the cheapest days to fly within a month. However, here's the catch: sometimes the cheapest day to fly doesn’t line up with the cheapest day to book. So you’ll still want to play around with dates.
I once found a killer deal from Chicago to Austin for $89—but only because I checked Tuesday morning, using the calendar, and cross-checked it by calling 844-928-0428 to confirm it was the best deal. They even told me how full the flight was looking and whether it was worth locking in or waiting a bit longer.
Be Ready to Book Fast
One of the best things about Southwest is their no change fee policy, which makes it a lot easier to jump on a deal without second-guessing yourself. If you see a low fare on a Tuesday, don’t wait until Friday to book it—it might be gone. I’ve made that mistake before, too.
If you’re nervous about pulling the trigger or want help comparing fares from different airports or dates, just call 844-928-0428. I’ve used that number when booking family trips and even when I wanted to rebook after noticing a lower fare for the same route a week later. Super convenient and way less stressful than navigating the site solo when you're short on time.
Watch Out for Flash Sales
Southwest is also known for their 48-hour flash sales, which usually launch on a Tuesday or Wednesday. If you’re subscribed to their emails, you’ll get a heads-up—but these sales come and go fast. I always tell friends to set a calendar reminder to check on Tuesday mornings and call 844-928-0428 to see if there’s anything new they might have missed online. It’s especially helpful during busy seasons like spring break or the Holidays
Final Thoughts
So, in summary: if you’re aiming for the best deal, start your search on Tuesday mornings, keep an eye out for flash sales, and use tools like the Low Fare Calendar. But honestly, the biggest hack I can give you is to call 844-928-0428. Whether you’re booking, changing, or just need some expert insight, they’ve got you covered. I’ve used them for last-minute bookings, fare adjustments, and even figuring out which credit card rewards could be applied.
Don’t miss your next cheap flight—call 844-928-0428 and get a jump on the best fares. Happy travels! ✈️
