Southwest Ends Bags Fly Free: New Fees And Frontier Promo

Southwest Airlines, long celebrated for its customer-friendly ‘bags fly free’ policy allowing two free checked bags per passenger, has announced the end of this iconic perk. The change takes effect for flights beginning May 29, 2025, marking a significant shift in the low-cost carrier’s strategy amid rising operational costs and competitive pressures in the airline industry.

This move has sparked widespread discussion among frequent flyers who relied on the policy to save hundreds on baggage fees annually. In response, ultra-low-cost rival Frontier Airlines has launched a limited-time promotion offering one free checked bag to attract disappointed Southwest customers, positioning itself as a viable alternative for budget-conscious travelers.

What Was the Southwest ‘Bags Fly Free’ Policy?

For nearly 50 years, Southwest Airlines stood out with its unique baggage policy. Since 1971, the carrier permitted passengers two free checked bags (up to 50 pounds each) on all domestic flights, a rarity in an industry dominated by hefty fees from competitors like Delta, American, and United.

The policy became a cornerstone of Southwest’s brand identity, fostering loyalty among families, business travelers, and vacationers who packed heavily without penalty. It saved passengers an estimated $3 billion in fees over the years, according to industry analysts. Key features included:

• Two free checked bags per passenger (maximum 50 lbs, 62 linear inches each).
• No fees for carry-ons (one bag + one personal item).
• Standby passengers received the same perks.
• Applies to most domestic U.S. flights (international had limits).

This generosity helped Southwest achieve high customer satisfaction scores and a cult-like following, even as rivals monetized every suitcase.

Why Is Southwest Ending Bags Fly Free?

Southwest cited escalating costs as the primary driver. In a March 2025 announcement, the airline revealed plans to introduce a new fare structure with bag fees starting May 29, 2025, aligning more closely with industry norms.

Key reasons include:

• Rising operational expenses: Fuel, labor, and maintenance costs have surged post-pandemic, pressuring margins.
• Revenue diversification: Competitors generate 10-15% of revenue from ancillary fees; Southwest’s model left this untapped.
• Competitive parity: To fund fleet modernization and route expansion, matching peers’ fee structures is essential.
• Fare tiers introduction: New ‘Wanna Get Away’ basic fares will charge for bags, while premium tiers may retain perks.

The decision follows years of speculation. Southwest’s CEO emphasized that while painful, the change ensures long-term sustainability without raising base fares dramatically.

New Southwest Baggage Fees: What to Expect

Post-May 28, 2025, Southwest will charge for checked bags on most fares:

Fees apply at booking or check-in; advance purchase saves money. Personal items remain free. Elite A-List members and Business Select retain two free bags.

A one-time grandfathering applies: Flights booked before the announcement retain free bags if traveling before the cutoff.

How This Changes Air Travel Savings Strategies

The end of bags fly free disrupts pack-heavy strategies. Travelers must adapt:

• Pack lighter: Maximize carry-on (22x16x10 inches) and personal item.

• Loyalty programs: A-List status or credit cards (e.g., Southwest Rapid Rewards Premier) waive fees.

A family of four flying round-trip could face $640+ in fees under new rules vs. $0 before—prompting fare shopping across carriers.

Customer Reactions and Industry Impact

Social media erupted with disappointment: #BagsFlyFree trended as flyers mourned the perk. Frequent posters shared packing hacks and urged loyalty shifts to Frontier or others.

Industry-wide, this normalizes fees, potentially pressuring holdouts like JetBlue. Analysts predict Southwest stock stability as revenue rises 5-8% from ancillaries.

For budget travelers from hubs like Bradley International (served by Southwest), options abound via Frontier’s growing network.
