Southwest Airlines offers a convenient option known as Southwest EarlyBird Check-In, designed to enhance your travel experience by providing an easier and more relaxed boarding process. With EarlyBird Check-In, you can secure an earlier boarding position without the need to manually check in right at the 24-hour mark before your flight. Instead, the airline automatically assigns your boarding position 36 hours before departure, giving you a better chance to select your preferred seat and ensuring space for your carry-on luggage in the overhead bin.
