Cheapest Day to Book Southwest Flights

Tuesdays are generally the best and cheapest day to book Southwest Airlines flights, according to Justflydeals. The airline often launches fare sales on Tuesdays, which typically run through Thursday. In addition, Southwest frequently drops prices on select routes every Tuesday, giving travelers a prime opportunity to grab low fares.

You refreshed Southwest’s website for the third time today, and those flight prices are doing the cha-cha again. Yesterday, it was $127; this morning, it jumped to $189, and now it’s somehow $156. Your mouse hovers over “Book Now” like you’re defusing a bomb—click too early, and prices might drop tomorrow; wait too long, and you’re paying rent money just to fly to Denver.

Sound familiar? Welcome to the airline pricing lottery, where the house always seems to win, and passengers are left playing guessing games with their vacation budgets. Unless they know the cheapest day to book Southwest flights.

But here’s the thing about Southwest’s pricing circus: there’s actually a method to the madness. But there are real tricks that can save you serious cash without needing a crystal ball or a degree in airline economics.

Strategies for Saving Money on Flights with Southwest Airlines

1. Book Early for the Best Prices

Southwest flights are like concert tickets—they start cheap and get pricier as seats disappear. That $89 fare you saw last week? It’s probably wearing a tuxedo and costs $200 now. Book early to catch those sweet deals before they vanish into thin air.

2. Use Southwest Rapid Rewards Points

Points are your ticket to flying smart. When Southwest has sales, your points stretch further than yoga pants. Instead of paying cash during peak times, use points when prices are low. It’s like shopping with coupons that actually work.

3. Use Gift Cards and Travel Credits

Those Southwest credits from canceled flights aren’t just digital dust—they’re real money waiting to be spent. Check your balance before booking new flights on the best day to book Southwest flights. It’s like finding forgotten cash in your Southwest account wallet.

4. Set Fare Third Party Alerts

Let Google Flights, Hopper, or Kayak be your flight stalkers. They’ll watch prices 24/7, so you don’t have to. When fares drop, they’ll ping you faster than your mom texts about dinner plans. Then, book directly with Southwest.

How to Find Cheap Flights on Southwest Airlines?

1. Use Southwest’s Low Fare Calendar for Maximum Savings

Southwest’s Low Fare Calendar is your best friend when hunting for deals. Instead of picking specific dates and hoping for the best, this tool shows you the cheapest fares across an entire month. You’ll quickly see which days offer rock-bottom prices and which ones will drain your wallet. Being flexible with your travel dates can save you serious cash – sometimes, shifting your trip by just one day, especially on the cheapest day to book Southwest flights, can slash the cost by half. You can access this calendar from their official website. If your vacation dates aren’t carved in stone, spend a few minutes exploring different options. 

2. Stay Alert for Tuesday Sales and Flash Deals

Southwest loves dropping surprise sales, and Tuesdays are their favorite day to do it. These aren’t just small discounts – we’re talking about fares that can drop by $100 or more per ticket. The key is staying in the loop through their Click ‘N Save emails, which land in your inbox every Wednesday. Southwest also runs flash sales that last just 72 hours, so you need to act fast when you spot a good one. Don’t wait to “think about it” because these deals disappear quickly. Set up price alerts for routes you’re interested in, and when Southwest sends those sale notifications, take a few minutes to check if your destinations are included that’s a smart way to know when to book Southwest flights. Many travelers save hundreds just by being ready to book when sales hit.

3. Fly During Weekdays and Off-Peak Hours

Here’s a money-saving secret: Weekday flights, especially Tuesdays and Wednesdays, cost way less than weekend departures because fewer people want to travel mid-week. Early morning flights and late evening red-eyes are cheaper, too, since most folks prefer convenient times. If you can handle a 6 AM departure or don’t mind landing at 11 PM, you’ll pocket the savings. Business travelers pack Monday and Friday flights, driving up prices. In contrast, Sunday flights cost more because everyone’s heading home from weekend trips. Even shifting your travel by one day can save $50-150 per person. 

FAQs for Cheapest Southwest Flights Deals

On which day of the week is the best and cheapest way to book a Southwest flight?

Tuesday afternoons often present better deals, but don’t hesitate if you find a solid fare on a different day. Booking 6-8 weeks out should outweigh which day fares are cheaper. 

What day of the week does Southwest have sales?

Southwest usually announces sales on Tuesdays, and Click ‘N Save emails come out on Wednesdays. Southwest also has flash sale promotions throughout the week that last for 72 hours, offering great Southwest flight deals.

When is the ideal time to book Southwest flights?

Book at least 6-8 weeks for domestic travel and 8-10 weeks for holiday travel. Anytime before 3 months out, you will likely avoid booking because prices are usually higher, and expensive last-minute price hikes will occur.

If the price drops after booking, will I get a refund?

Southwest does not automatically refund you for price drops; however, there are a couple of options. You can simply cancel and rebook on the cheapest day to book Southwest flights (since they don’t charge change fees), which allows you to receive a credit for the difference in fares.
