How to Get the Best Price on Southwest Airlines in 2026
Getting cheap Southwest flights takes a bit of strategy. Here’s what works:
- Use the Southwest Low Fare Calendar
The Southwest Low Fare Calendar shows the cheapest available fares across an entire month — ideal for travellers with flexible dates. - Book on Tuesdays or Wednesdays
Southwest typically releases fare sales mid-week. Prices on Tuesdays and Wednesdays are often 10–20% lower than weekend fares on popular routes. - Sign Up for Price Alerts
Subscribe to Southwest email alerts for flash sales and limited-time promotions. Sale fares on select routes can drop as low as $39 one-way. - Book Early
Prices generally increase as the departure date approaches. Booking 3–6 weeks in advance typically yields the best Southwest Airlines flight deals. - Rebook If Fares Drop
If a fare drops after you book, Southwest allows you to rebook at the lower price via Manage Booking and receive a travel credit for the difference, a major advantage over most U.S. carriers.
