Southwest Airlines offers a convenient and flexible seat selection process for its passengers. During the booking process, passengers can choose to either select their Southwest Seat Selection seats for an additional fee or opt for a free random seat assignment. The airline also offers a unique boarding process, which eliminates the need for assigned seats altogether. Passengers are assigned a boarding group and position within that group, and can then choose any available seat once they board the plane. This allows for a stress-free and efficient boarding process for both passengers and crew. With Southwest's seat selection options, passengers can choose the option that best suits their needs and budget.
