When Does Southwest's New Bag Policy Start

Let’s be real—Southwest’s free bag policy is basically legendary. For years, it’s been the one airline that lets you pile on a carry-on and two checked bags without a single fee. That’s huge for anyone who hates hidden costs or travels with a family. But with recent rumors swirling, everyone’s asking: when does Southwest’s new bag policy start? The official word is that as of May 28, 2025, Southwest will begin charging for checked bags on most fares—except for its top-tier Rapid Rewards members and Business Select ticket holders.

Why does this matter? Because it’s a game-changer for your wallet. For years, families could check everyone’s suitcase for free, saving $100 to $300 per trip. Now, that perk is narrowing. If you’re a casual flier, you’ll need to plan ahead to avoid surprise fees. It’s a shift that rewards loyalty, but it also means budget-conscious travelers must rethink packing strategies.

Here’s a real-life example: Meet the Carter family of four. They used to check four bags free on their annual Florida vacation. Starting June 1, that’s a potential $140 extra cost. On the flip side, solo traveler Jen, who flies Southwest monthly for work, will still enjoy free bags if she keeps her Rapid Rewards status. The benefit is clear: loyal customers are protected, while occasional fliers feel the pinch.

Want to make this work for you? First, sign up for Rapid Rewards immediately—it’s free and could grandfather you into free bags if you book early. Second, learn to pack efficiently: use a carry-on to its max and limit checked bags to one per person. Third, always book Business Select if your budget allows—it includes two free checked bags and priority boarding.

Finally, don’t panic. This change rolls out gradually, so you have time to adjust. Use the Southwest app to check bag fees before you fly. For now, the airline’s new bag policy starts May 28, 2025 for new bookings. With a little savvy, you can still travel light and smile.
