What is EarlyBird Check-In at Southwest? EarlyBird Check-In at Southwest Airlines is a paid service that allows passengers to automatically check in before the traditional 24-hour check-in period. This service is designed to provide travelers with a better boarding position, increasing their chances of securing a preferred seat on the aircraft. Southwest Airlines operates on an open-seating policy, meaning passengers are not assigned seats but instead choose their own upon boarding. Since boarding positions are assigned based on the check-in order, EarlyBird Check-In gives passengers a significant advantage by automatically checking them in 36 hours before departure, which is 12 hours earlier than standard check-in. This service is particularly beneficial for travelers who want to ensure a better seat selection without having to manually check in exactly at the 24-hour mark. EarlyBird Check-In at Southwest also helps passengers avoid the stress of last-minute check-ins, making the travel experience smoother and more convenient. The service is available for an additional fee, which varies depending on the flight route and demand. It is non-refundable and does not guarantee an A boarding group position, but it does increase the likelihood of getting a more favorable boarding spot compared to those who check in manually.
