Customers can get added to the same-day standby list in person at the airport on the day-of-travel with a Southwest Customer Service Agent at the ticket counter or departure gate or on the Southwest app or mobile web. If a seat becomes available for you on the flight, you will receive an email or text message (based on the flight status contact preference selected during booking) with a link to check in to receive your new boarding pass via the Southwest app or mobile web. You can also visit a Southwest Customer Service Agent at the ticket counter or departure gate to request the boarding pass.​
