In a bold move to attract budget-conscious travelers, Frontier Airlines announced a limited-time promotion offering free checked bags on flights booked during a 24-hour sale window, directly challenging Southwest Airlines’ long-standing “bags fly free” policy. This strategic play, revealed on March 18, 2025, marks Frontier’s latest effort to position itself as a cost-effective alternative in the competitive U.S. airline market. Here’s how the promotion works, why it matters for travelers, and what this rivalry means for your next trip.
Frontier’s Free Checked Bags: Limited-Time Promo Details
For the first time in its history, ultra-low-cost carrier Frontier Airlines is waiving checked baggage fees for passengers booking flights between March 18–19, 2025. The deal applies to:
- 1 free checked bag (up to 40 lbs / 18 kg) per passenger on qualifying domestic U.S. routes.
- Travel dates valid through December 14, 2025.
- Bookings must be made directly through Frontier’s website or app.
This promotion is a significant departure from Frontier’s usual à la carte pricing model, where checked bags typically cost 35–60 each way. Analysts suggest the move is designed to capture attention amid rising competition from Southwest, which has built customer loyalty by allowing two free checked bags on all flights since 2009.

Southwest’s Response: Doubling Down on “Bags Fly Free”
Southwest Airlines quickly responded to Frontier’s promo, reaffirming its commitment to its industry-unique policy of no fees for two checked bags (up to 50 lbs / 23 kg each) on every ticket. A Southwest spokesperson noted, “Our customers value transparency and simplicity. While others offer temporary perks, our policy is permanent—no surprises, no expiration dates.”
Southwest also highlighted its recent expansion of routes to Mexico and the Caribbean, catering to travelers seeking international getaways without baggage hassles.
Why This Matters for Travelers—Especially International Visitors
For Asian travelers planning U.S. trips, baggage policies can make or break a budget. Here’s how both airlines compare:
| Airline | Free Checked Bags | Weight Limit | Route Applicability |
|---|---|---|---|
| Frontier (Promo) | 1 bag | 40 lbs / 18 kg | Domestic U.S. only |
| Southwest | 2 bags | 50 lbs / 23 kg | All routes (incl. international) |
Key Takeaways:
- Frontier’s promo is ideal for short domestic trips (e.g., Las Vegas, Miami, or Denver).
- Southwest remains the better choice for longer vacations or international travelers needing extra luggage space.
- Always compare total costs: Frontier’s base fares are cheaper, but add-ons (seats, carry-ons) can negate savings.
Expert Tips for Maximizing These Deals
- Pair with Hotel Discounts: Use baggage savings to upgrade accommodations. HotelInfoAsia.com partners with U.S. hotels offering exclusive rates for international guests.
- Watch for Blackout Dates: Frontier’s promo excludes peak holiday periods (Thanksgiving, Christmas).
- Loyalty Programs Matter: Southwest’s Rapid Rewards points never expire, while Frontier’s Discount Den membership ($59/year) offers bundled savings.
Industry Outlook: A Shift in Budget Travel?
Aviation analysts predict more airlines will experiment with bundled perks to lure travelers tired of “fee fatigue.” “Frontier’s promo tests whether baggage inclusivity can drive long-term loyalty,” says travel expert Maria Chen. “However, Southwest’s consistent policy still holds an edge for family and group travelers.”
For Asian travelers, this competition could signal better deals on U.S. routes, especially when combined with aggressive pricing from Asian carriers like AirAsia X and Zipair Tokyo on trans-Pacific flights.
