Online Check In on Southwest
Southwest online check in opens 24 hours before your flight and closes 30 minutes prior to departure for most domestic flights. This window gives you enough time to select seats, print or save your boarding pass, and confirm bag options without pressure at the airport.
To use online check in, you need a booking reference and the traveler’s first and last name exactly as shown on the ticket. The system works on both desktop and mobile browsers, and the Southwest app offers an even faster way to manage your trip once it is downloaded and signed in.
Completing Southwest check in online reduces time at the kiosk or counter, especially when you already know your seating preferences. You can review flight details, assign seats if still available, and prepare your boarding method before arriving at the airport.
Airport Kiosk and Counter Options
Using Self Service Kiosks
Southwest kiosks are available at most airports starting 24 hours before departure. Swiping an ID, entering a confirmation number, or scanning a mobile boarding pass can quickly generate a boarding tag, and many travelers use the kiosk even when checking bags to speed up the process.
Visiting the Ticket Counter
If you need extra help, have complex connections, or want to check multiple bags, the ticket counter is the best option. Agents can assist with name corrections, special assistance, and itinerary changes that may not be possible through automated channels.
Baggage and Boarding Procedures
Southwest does not charge checked bags, but fees may apply in certain circumstances such as international flights or specific fare rules, so it is important to verify current pricing at the time you check in. Bags are usually handled on a first checked, first loaded basis when processed correctly at check in.
Boarding groups are assigned based on fare type, EarlyBird check in purchase, and priority status, which influences when you can enter the jetway. Choosing your seat during online or kiosk check in can improve your boarding position if seats are still open, while A1–A15 and other priority groups board earlier than general groups.
