Key takeaways
Southwest Airlines is ending free checked bags on a significant portion of its flights. The change mainly applies to flights operated by partner airlines and some higher-fare cabins, effective in stages starting in 2025. Travelers who fail to adjust their plans risk checked-bag fees at the gate. Below are practical details, timelines, and alternatives to manage costs.
What the change means for passengers
For decades, Southwest has included two free checked bags in most fares. The new policy removes that benefit on certain flights, typically those operated by regional partners or in premium cabins. Passengers on mainline Southwest flights will generally retain free checked bags, but it is essential to verify the flight code and fare rules. Expect to pay checked-bag fees on selected routes, which can add up quickly for families or travelers with multiple bags.
Which flights will be affected
Not every Southwest ticket will lose free checked bags. Routes operated by partner airlines under capacity purchase agreements are the primary targets, along with certain business-select and flex fares. International itineraries and specific leisure bundles may also see changes. Always review the reservation details or check the airline’s official policy portal before booking to confirm bag allowances.
When the policy changes take effect
The rollout occurs in phases through 2025 and beyond. Some partner flights began charging for checked bags in early segments of the year, while others follow later. Because implementation varies by flight and contract, passengers should check their itinerary’s effective date and reconfirm closer to departure.
How fees and alternatives compare
Without free checked bags, travelers can expect fees similar to mainline carriers for checked luggage, often starting around $30 for the first bag on many major airlines. Southwest still offers generous checked bag allowances on its own flights, but the shift on partner routes narrows that advantage. Below is a concise comparison of checked bag policies and typical first-bag fees.
| Airline type | Checked bags included in economy | Typical fee for first checked bag | Verification source |
|---|---|---|---|
| Southwest mainline | 2 free checked bags (most fares) | N/A when included | Southwest policy documents |
| Partner-operated flights | 0–1 free checked bag (varies) | $30–$40 | Public fare rules and airline disclosures |
| Legacy carriers | 0–1 free checked bag (economy) | $30–$35 | Published tariff and fare rules |
Practical steps to avoid unexpected fees
- Check your reservation’s bag details in your booking and at check-in, not historical assumptions.
- Look for the operating airline code on your ticket; partner flights are more likely to impose fees.
- Consider purchasing checked bags in advance online, which is usually cheaper than gate fees.
- Downsize luggage or use carry-on when feasible to sidestep checked-bag charges altogether.
- Review fare rules; some higher fares or memberships may retain benefits despite the policy shift.
Why Southwest is making this change
Southwest cites competitive pressures and cost simplification across its network as reasons for adjusting bag benefits on select flights. By aligning certain routes with partner economics, the airline can better manage costs and staffing at regional airports. While free checked bags remain strong on core Southwest flights, the reduction on partner operations reflects broader industry tradeoffs between fare levels and included services.
Impact on frequent travelers and loyalty
Baggage-policy changes disproportionately affect business travelers and heavy road warriors who rely on predictable fees. Frequent-flyer members keep earning and redeeming points, but they may see higher out-of-pocket costs on partner itineraries. Southwest’s A-List and A-Select status still offer perks, yet travelers should weigh these against checked-bag fees when choosing fares and routes.
Bottom line for travelers
Southwest’s move to remove free checked bags on some flights is a significant shift for passengers used to a no-fee experience across the board. Mainline travelers remain largely unaffected, while those on partner-operated routes should budget for checked-bag costs and verify allowances before booking. By checking your specific itinerary, buying bags in advance, and choosing appropriate fares, you can minimize surprises and manage expenses effectively.
