After you receive a Southwest confirmation, review the reservation before you consider the trip finished. Check every passenger’s name, airports, dates, times, connections, fare type, seat assignment, baggage allowance, and contact information. Then add any missing Rapid Rewards or Known Traveler numbers, save the confirmation, and check in when the 24-hour window opens.
Quick Answer
After booking a Southwest flight, verify the passenger names and itinerary, review the fare and seat rules, confirm baggage costs, add loyalty and security numbers, and save the confirmation. Check in within 24 hours of departure, but remember that Southwest now uses assigned seats and Groups 1 through 8 rather than open seating.
Key Takeaways
- Make sure each passenger’s name matches the identification they will use for travel.
- Southwest has assigned seating. Your fare, seat location, status, and card benefits affect seat choice and boarding group.
- Basic is the most restrictive fare. Choice, Choice Preferred, and Choice Extra offer more flexibility.
- Most Southwest credit card benefits require the primary Cardmember to travel on the same reservation and include their Rapid Rewards number.
- Check in before the cutoff and be in the gate area with a boarding pass at least 10 minutes before departure.
At a Glance
| Time Required | About 10 to 15 minutes after booking, plus check-in before departure |
| Difficulty | Easy |
| Tools Needed | Confirmation email, Southwest app or website, travel ID, and passport for international travel |
| Cost | Free to review and check in; baggage, seat, fare-difference, or optional boarding charges may apply |
What to Check on Your Southwest Confirmation
Start with the six-character confirmation number and the name of each passenger. The name on the reservation should match the government-issued identification or passport the traveler will present. Small formatting differences may be accepted, but a wrong first or last name should be corrected before travel.
- Route: Confirm the departure and arrival airports, including airport codes. Cities with several airports are a common source of mistakes.
- Date and time: Check the local departure date, arrival date, time zone, and whether the flight is overnight.
- Connections: Review each flight number, connection airport, and layover length.
- Fare and seat: Confirm the fare bundle and the seat selected or assigned for every flight segment.
- Contact details: Make sure Southwest has a working mobile number and email address for schedule alerts.
- Traveler numbers: Add the correct Rapid Rewards number, Known Traveler Number, or redress number when applicable.
- International documents: Confirm passport details and destination entry requirements well before departure.
Adults flying within the United States should also verify that they have a TSA-accepted form of identification. A noncompliant state ID may not be accepted at the security checkpoint.
Note: Take a screenshot or save the confirmation email offline. You may need the confirmation number to check in, retrieve the trip, track a bag, or get help when connectivity is limited.
Southwest Fare Types and What They Allow
Southwest offers four main fare bundles for travel with assigned seating. The differences affect seat selection, boarding, points, changes, refunds, flight credits, and checked bags. Review the current Southwest fare benefits before changing or canceling a reservation.
| Fare | Seat and boarding | Changes, credits, and bags |
|---|---|---|
| Basic | A Standard seat is assigned at check-in or the gate unless another seat benefit applies. Preferred or Extra Legroom seats may be purchased when available. Basic boards last. | Earns 2 points per dollar. Nonrefundable and not changeable unless upgraded. An eligible credit generally expires six months from the original booking date. Checked bag fees may apply. |
| Choice | Choose a Standard seat at booking. Preferred or Extra Legroom seats may be purchased when available. General boarding applies. | Earns 6 points per dollar. Changes are allowed with any fare difference. Includes same-day change or standby when eligible. A Transferable Flight Credit generally expires 12 months from booking. Checked bag fees may apply. |
| Choice Preferred | Choose a Preferred or Standard seat at booking. Extra Legroom may be purchased when available. Typical fare-based boarding is Groups 3 to 4. | Earns 10 points per dollar. Refundable when canceled on time. Changes, same-day change, and standby are available. Checked bag fees may apply. |
| Choice Extra | Choose an Extra Legroom, Preferred, or Standard seat at booking. Fare-based boarding is Group 1. | Earns 14 points per dollar. Refundable when canceled on time. Includes changes, same-day change, two standard checked bags, and a premium drink on select flights. |
Basic can make sense when your plans are firm, but it does not become flexible simply because you have a Southwest credit card. Choice is often a practical middle option because it includes seat selection, changes, and same-day flexibility. Choice Preferred and Choice Extra cost more but add refundability and earlier boarding benefits.
Warning: Cancel at least 10 minutes before the flight’s original scheduled departure. A no-show can cause funds or points to be forfeited under the fare rules.
How to Change or Cancel a Southwest Booking
Open the trip in the Southwest app or on Southwest.com and review the fare rules before making a change. Choice, Choice Preferred, and Choice Extra can be changed, although you may owe a fare difference. A Basic fare must be upgraded before it can be changed.
- Within 24 hours of booking: Southwest allows an unchanged reservation to be canceled for a refund to the original payment method or held as the applicable flight credit.
- After 24 hours: Refund or credit treatment depends on the fare and any funds previously applied to the ticket.
- Round trips with Basic: If either segment is Basic, you generally must cancel the full round trip or upgrade the Basic segment before canceling only part of it.
- Southwest schedule changes: If Southwest cancels or significantly changes the flight, open the reservation and review the rebooking and refund options shown for that trip.
Check the expiration date displayed for any flight credit. Travel normally must be completed by that date, not merely booked by it.
How Southwest Credit Cards Change the Deal
A Southwest Rapid Rewards credit card can add baggage, seating, and boarding benefits, but the exact benefit depends on the card. The primary Cardmember must normally be traveling on the reservation, the card account must be eligible, and the Cardmember’s Rapid Rewards number must be included. Review the current Rapid Rewards Cardmember benefits before relying on a perk.
Free Checked Bag Perks
The primary Cardmember and up to eight additional passengers on the same reservation can each receive their first standard checked bag at no additional cost. Oversize, overweight, and extra-bag charges may still apply, and the benefit may not apply to partner-operated itineraries.
- The Cardmember must remain on the same reservation.
- The Cardmember’s Rapid Rewards number must be attached to the booking.
- Authorized users do not receive the primary Cardmember benefit when traveling without the primary Cardmember.
This benefit can save money for a family or group, but compare the annual fee and other card terms with how often you actually fly and check bags.
Booking With Cardholder
Put the primary Cardmember and the travelers who need the shared benefits on the same reservation whenever their plans match. This can extend the first-bag and Group 5-or-earlier boarding benefits to as many as eight additional passengers.
Companion Pass travel works differently. The pass holder books their own flight first and then adds the designated Companion, whose reservation mirrors the pass holder’s trip. Do not assume that a Companion booking follows every rule that applies to a normal group reservation.
Seat Selection Advantages
Card seating benefits vary by product and remain subject to availability:
- Plus: A complimentary Standard seat may be selected within 48 hours of departure.
- Premier: A complimentary Preferred or Standard seat may be selected within 48 hours of departure.
- Priority: A complimentary Preferred or Standard seat may be selected at booking, with an Extra Legroom upgrade available within 48 hours when space remains.
Similar benefits apply to the related business cards. Cardmembers and up to eight additional passengers on the same reservation also board no later than Group 5 when the benefit applies. These perks improve seating and boarding, but they do not remove Basic fare change restrictions or extend its credit expiration.
Should You Book Everyone on One Reservation?
Booking everyone together is usually helpful when the travelers share the same flights and need the same card or tier benefits. Passengers on the same standard reservation normally receive the same boarding group, and eligible Cardmember benefits can extend to up to eight additional passengers.
Booking Together Benefits
- You can manage the itinerary from one confirmation number.
- Eligible card, tier, and boarding benefits can apply across the reservation.
- Seat selection is easier to coordinate when the fare includes it.
- Schedule changes are easier to review for the whole party.
For families, do not rely only on automatic seat assignment. Southwest says it will work to seat children age 12 and younger next to at least one accompanying adult when seats are limited, but choosing Choice or a higher fare, or purchasing seats, gives you more control.
Cardholder Must Be Included
The primary Cardmember must be a passenger on the reservation for shared seating, boarding, and checked-bag benefits to apply. The Rapid Rewards number should also be included. Removing the Cardmember can cause complimentary seat selections to be released and the remaining travelers to be handled under their own fare rules.
Split Reservations Risks
Separate reservations can be useful when travelers may return on different dates or need different fares. However, splitting the group can also mean separate check-ins, separate schedule-change handling, and the loss of shared Cardmember or tier benefits for travelers who are no longer on the eligible member’s reservation.
- Do not split a reservation only to chase a better boarding group.
- Confirm who will keep card and tier benefits before dividing a booking.
- For children, verify the seat assignments immediately after any split or change.
When to Book Southwest Flights for Flexibility
There is no guarantee that the first published fare will be the lowest. Southwest recommends shopping early and checking often because fares can change at any time. Use the Low Fare Calendar, compare nearby dates, and review the restrictions before choosing the cheapest fare.
| When | What to do | Important limit |
|---|---|---|
| Before booking | Compare the Low Fare Calendar, flight times, seat choices, bag costs, and credit rules. | The lowest displayed fare is usually Basic and has the most restrictions. |
| Within 24 hours | Correct mistakes or cancel the unchanged reservation if the trip no longer works. | Optional charges and special booking types can have separate rules. |
| After booking | Monitor the same flights for a lower fare. | Basic must be upgraded before a voluntary change. |
| Before departure | Review flight status, airport guidance, seat assignment, and bag payment. | Credits and refunds depend on the fare and cancellation timing. |
Pro Tip: When a Choice or higher fare drops, use the change tool to compare the new total before confirming. A refundable fare may return the difference to the original payment method, while Choice normally produces a Transferable Flight Credit.
One-Way vs Round-Trip Southwest Bookings
Neither structure is always best. A round trip keeps both directions under one confirmation, while separate one-way reservations let you change or cancel one direction without opening the other trip.
- Choose a round trip when the same travelers will use both flights and you want simpler reservation management.
- Consider separate one-ways when the return plan is uncertain, different passengers may return separately, or you want each direction handled independently.
- Be careful with Basic: On a round trip with a Basic segment, Southwest generally requires canceling the full round trip or upgrading the Basic segment before a partial cancellation.
Separate one-way bookings also create separate confirmation numbers. Cardmember and tier benefits must qualify on each reservation, so keep the eligible traveler on every booking that needs those benefits.
How Does Southwest Check-In Work?
Southwest check-in opens 24 hours before the flight’s original scheduled departure. You can check in through the app, Southwest.com, a self-service kiosk where available, a Skycap podium at select airports, or the ticket counter. You will need the confirmation number and the first and last name of a passenger on the itinerary.
Southwest changed from open seating to assigned seating on January 27, 2026. Checking in at exactly 24 hours no longer lets most passengers race for an open seat.
Check-In Timing
Check in promptly so you can retrieve the boarding pass, confirm the seat, and fix any problem before travel. For Basic fares, a Standard seat is normally assigned at check-in or at the gate. However, boarding group and seat choice now depend mainly on the fare, selected seat, Rapid Rewards status, and eligible credit card benefits, not simply on who checks in first.
- Domestic check-in cutoff: 30 minutes before original scheduled departure.
- International check-in cutoff: 60 minutes before departure, or 75 minutes for Aruba.
- Checked-bag acceptance: At least 45 minutes before a domestic flight and 60 minutes before an international flight, or 75 minutes for Aruba.
- Gate requirement: Have a boarding pass and be in the gate area at least 10 minutes before departure.
Airport and security wait times vary. Check Southwest’s airport information for your departure airport and leave enough time to meet every cutoff.
Check-In Methods
| Method | How it works | Best for |
|---|---|---|
| Southwest app | Retrieve the reservation, check in, view the seat, and save a mobile boarding pass. | Most travelers |
| Southwest.com | Enter the confirmation number and passenger name, then print or save the pass. | Desktop access or group review |
| Kiosk or Skycap | Check in, print documents, review the seat, and tag bags where available. | Airport self-service |
| Ticket counter | An Agent can verify documents, help with special cases, and accept bags. | International documents or extra support |
For an itinerary involving a partner airline, check in with the carrier operating the first flight. Some international routes also require document verification at the airport.
Boarding Pass Deadlines
Do not confuse the check-in cutoff with the gate deadline. Even after checking in online, you must have the boarding pass and be in the gate area at least 10 minutes before the original scheduled departure. Southwest may cancel the reserved space when a passenger misses that requirement.
- Save the mobile pass to your phone wallet or take a screenshot.
- Recheck the gate in the app and on airport screens.
- Allow extra time if you need to check bags or verify international documents.
Southwest Boarding Groups and Seat Choice
Southwest now assigns seats and uses boarding Groups 1 through 8. You keep the seat shown on your boarding pass, so boarding earlier mainly improves access to overhead bin space rather than giving you first choice of open seats. Review the current Southwest boarding process for special boarding needs and current group details.
- A-List Preferred: Boards before Group 1.
- A-List and Choice Extra: Generally board in Group 1 when that is the highest applicable benefit.
- Choice Preferred: Fare-based boarding is generally Groups 3 to 4.
- Choice: Standard or Preferred seats generally board in Groups 3 to 7.
- Basic: Normally boards in Group 8 unless a better status or card benefit applies.
- Eligible primary Cardmembers: Board no later than Group 5, with the benefit extending to up to eight additional passengers on the same reservation.
Boarding groups can also depend on seat type and cabin location. Use the group printed on the boarding pass rather than assuming a position from the fare alone.
Southwest Bags and Digital Bag Tracking
A carry-on bag and personal item are included, but checked-bag fees may apply to Basic, Choice, and Choice Preferred. Choice Extra includes two standard checked bags. Eligible A-List and credit card benefits can change the allowance.
For U.S. mainland travel booked, ticketed, or changed on or after April 9, 2026, Southwest lists a standard first checked bag at $45 and a second at $55 for Basic, Choice, and Choice Preferred. Fees and exceptions can change, so verify the optional travel charges for your exact trip.
- Standard checked-bag size: Up to 62 linear inches, including wheels and handles.
- Standard checked-bag weight: Up to 50 pounds.
- Online bag payment: Available during or after online check-in for eligible trips.
- Bag tracking: Search by confirmation number or bag tag number and passenger name.
Southwest’s digital bag tracker can show loading and unloading scans, including on connections. A missing scan does not always mean the bag missed the flight. If the bag does not arrive, go to the Baggage Service Office and file a report.
Southwest WiFi, Snacks, and Entertainment
Rapid Rewards members receive free WiFi where available on designated aircraft. Nonmembers may be able to buy access for $8 per device. Starlink is available on select aircraft, and availability can change if the aircraft is swapped.
- On many WiFi-equipped aircraft, the free entertainment portal offers movies, TV, and flight information on your own device.
- On Starlink-equipped aircraft, the onboard entertainment portal may not be available, but travelers can use WiFi to stream from their own services.
- Southwest does not provide seatback screens or rent devices, so charge your phone or tablet and bring headphones.
- Snack and drink service is offered on select flights of 251 miles or more. You may bring your own food.
- Alcohol consumed onboard must be served by Southwest. Premium beverages may be sold on eligible flights.
Check the latest Southwest onboard experience and WiFi information before departure because aircraft features and service can vary.
Frequently Asked Questions
What is Southwest’s senior discount policy?
Southwest does not currently offer senior fares. Travelers age 65 or older can compare the same Basic, Choice, Choice Preferred, and Choice Extra fares offered to other customers and use the Low Fare Calendar or eligible promotions.
What is the 3-1-1 rule on Southwest?
The 3-1-1 liquids rule is a TSA security rule, not a Southwest fare rule. Most carry-on liquids, aerosols, gels, creams, and pastes must be in containers of 3.4 ounces or 100 milliliters or less and fit in one quart-size bag. Medical and infant-related exceptions may apply.
What is the golden rule at Southwest?
Southwest does not publish a passenger fare, baggage, or boarding policy called the “golden rule.” The phrase may be used informally to describe treating people with respect, but it does not replace the written Contract of Carriage or fare rules.
What is the 10-minute rule for Southwest?
You must have a boarding pass and be in the gate area at least 10 minutes before the original scheduled departure. You should also cancel a trip you will not take at least 10 minutes before departure to avoid the no-show policy.
Do I still need to check in exactly 24 hours before a Southwest flight?
Check-in still opens 24 hours before departure, and checking in promptly is useful for retrieving your boarding pass and viewing a Basic seat assignment. However, Southwest now has assigned seating, so check-in time does not give most passengers first choice of open seats.
Does Southwest still include free checked bags?
Not for every traveler. Choice Extra includes two standard checked bags. A-List, A-List Preferred, and eligible Rapid Rewards credit cards provide specific bag benefits. Basic, Choice, and Choice Preferred travelers without an exception may have to pay checked-bag fees.
Conclusion
After booking a Southwest flight, verify the reservation, match each name to the traveler’s ID, understand the fare and seat rules, and check the current baggage allowance. Keep the confirmation and travel documents easy to reach, monitor the flight, and check in within the 24-hour window. Assigned seating has removed the old race for open seats, but timely check-in and airport arrival still protect your trip.
