Southwest Baggage Fees Round Trip 2026
Understanding how Southwest charges baggage fees on round trip flights is essential for accurate trip budgeting. This comprehensive guide explains how fees apply to both outbound and return legs, with calculation examples for different scenarios.
How Round Trip Baggage Fees Work
Southwest treats each flight segment independently for baggage fees. Your outbound flight and return flight are charged separately, even if purchased together as a round trip ticket.
Outbound Flight (To Destination)
- • Bags checked at origin airport
- • Fees charged based on current status/fare
- • Each bag weighed and measured
- • Fees paid at initial check-in
- • Receipt provided for outbound segment
Return Flight (Back Home)
- • Bags checked again at destination airport
- • Separate fees apply for return segment
- • Same weight/size rules apply
- • Fees paid at return check-in
- • Separate receipt for return segment
Round Trip Fee Examples by Passenger Type
Here's what different passengers pay for round trip baggage fees under various scenarios:
Regular Passenger (No Status, Basic/Choice Fare)
| Bags | Outbound | Return | Round Trip Total |
|---|---|---|---|
| 1 bag | $35 | $35 | $70 |
| 2 bags | $80 | $80 | $160 |
| 3 bags | $230 | $230 | $460 |
A-List Member (1 Free Bag)
| Bags | Outbound | Return | Round Trip Total |
|---|---|---|---|
| 1 bag | $0 | $0 | $0 |
| 2 bags | $45 | $45 | $90 |
| 3 bags | $195 | $195 | $390 |
A-List Preferred or Choice Extra Fare (2 Free Bags)
| Bags | Outbound | Return | Round Trip Total |
|---|---|---|---|
| 1 bag | $0 | $0 | $0 |
| 2 bags | $0 | $0 | $0 |
| 3 bags | $150 | $150 | $300 |
Calculating Round Trip Overweight & Oversize Fees
Overweight and oversize surcharges also apply each way on round trip flights. These fees can add up quickly if you're traveling with heavy or large bags both directions.
| Scenario | One Way Cost | Round Trip Total |
|---|---|---|
| 1st bag, 65 lbs (overweight) | $35 + $100 = $135 | $270 |
| 1st bag, 75 lbs (overweight tier 2) | $35 + $200 = $235 | $470 |
| 1st bag, 70 linear inches (oversize) | $35 + $100 = $135 | $270 |
| 1st bag, 65 lbs + 70" (both) | $35 + $100 + $100 = $235 | $470 |
Do Free Bag Benefits Apply Both Ways?
Yes! If you have A-List status, a Southwest credit card, or book Choice Extra fare, your free bag benefit applies to BOTH your outbound and return flights.

What If Your Status Changes Mid-Trip?
Baggage benefits are determined by your status AT THE TIME OF EACH FLIGHT, not when you booked. This can work for or against you.
Status Gained Mid-Trip
If you earn A-List status after your outbound flight but before your return, your return flight gets the free bag benefit even if you paid outbound.
Example:
Fly out Monday (pay $35 for bag), earn A-List Wednesday, return Friday (1st bag free) - save $35 on return leg!
Status Expires Mid-Trip
If your A-List status expires between your outbound and return flights, you'll pay baggage fees on the return segment.
Example:
A-List expires Dec 31. Outbound Dec 30 (free bag), return Jan 2 (pay $35 for bag) - plan accordingly!
Round Trip vs One-Way Pricing
Southwest doesn't charge different baggage fees for round trip versus one-way tickets. The fees are the same per segment regardless of how you book.
| Booking Type | Outbound Bag Fee | Return Bag Fee | Total |
|---|---|---|---|
| Round trip ticket | $35 | $35 | $70 |
| Two one-way tickets | $35 | $35 | $70 |
Multi-City & Connecting Flights
For complex itineraries with multiple stops or connections, understanding when fees apply can save you money.
How Fees Apply to Different Itineraries
Direct Round Trip (No Connections)
Example: LAX to Dallas, return Dallas to LAX
Fees: Check bags at LAX (pay fees), collect in Dallas. Check bags at Dallas (pay fees again), collect at LAX.
Round Trip with Connections
Example: San Diego → Denver → New York, return same route
Fees: Pay once at San Diego (bags transfer automatically through Denver). Pay once at New York for return (bags transfer through Denver again).
Multi-City (Three+ Cities)
Example: Chicago → Phoenix → Las Vegas → Chicago
Fees: Pay at each originating city: Chicago (outbound), Phoenix (to Vegas), Las Vegas (return to Chicago) = 3 sets of baggage fees.
International Round Trip Considerations
Southwest's international routes to Mexico, Central America, and the Caribbean follow the same round trip baggage fee structure as domestic flights.

Common Questions About Round Trip Baggage Fees
Can I pay for round trip baggage fees upfront when booking?
No. Southwest does not allow you to pre-pay baggage fees when booking your ticket. Fees must be paid at the airport when you check your bags for each flight segment (outbound and return separately).
What if I only check a bag one way?
You only pay fees for the segments where you check bags. If you check a bag outbound but carry-on only for your return flight, you only pay the outbound bag fee. This is common when you buy items at your destination and ship them home instead.
Do I get a discount for checking bags both ways?
No. There's no "round trip discount" for baggage fees on Southwest. Each flight segment is charged independently at the standard rates ($35 first bag, $45 second bag, etc.) regardless of whether it's part of a round trip.
What if my return flight gets cancelled?
If Southwest cancels your return flight and you're rebooked, any baggage fees you already paid apply to the new flight. If you paid for checked bags on the cancelled flight, you won't be charged again when checking bags on the replacement flight.
Can I use a different credit card for free bags on my return flight?
Yes, as long as you used a Southwest Rapid Rewards credit card to purchase your ticket, the free bag benefit applies to the entire round trip journey regardless of which card you use to check in for individual segments.
How much can a family of 4 save with A-List Preferred on a round trip?
Significant savings! If each person checks 2 bags, that's 8 bags round trip. Without status: $640 (8 bags × $80 one-way × 2). With A-List Preferred giving 2 free bags per person: $0. Total savings of $640 for the family's round trip.
