Historically, Tuesdays and Wednesdays tend to offer lower fares, but this isn’t guaranteed because Southwest uses dynamic pricing. The best way to find the cheapest day is to call 831-298-4213. Agents can compare prices across dates, monitor fare drops, and suggest whether booking early or waiting could save you money. They can also check if rebooking with travel funds after a fare drop is beneficial. This personalized approach ensures you’re booking at the right time instead of relying on outdated fare myths.
