Next to checking in for a flight online, using a self-service kiosk is the quickest way to receive your boarding pass and Southwest has added functions to its airport kiosks so more passengers can take advantage of the speed and convenience. Lobby kiosks have been modified to allow passengers to change their itinerary on the day of travel, choose a new flight or add their name to the standby list for a different flight. Passengers will also be able to upgrade to Business Select when available and pay for any fare difference at all kiosk locations.
