On Southwest Airlines in 2026, the cost for priority boarding—known as Upgraded Boarding—typically ranges from $30 to $80 per segment, depending on the length of the flight and the demand for that specific route. This service allows you to secure a position in the coveted A1–A15 boarding group, ensuring you are among the first to board, choose your seat, and find overhead bin space. This can only be purchased starting 24 hours before departure if spots are available. Alternatively, you can purchase EarlyBird Check-In, which automatically checks you in 36 hours before the flight to get a better boarding position (usually in the A or early B groups). EarlyBird costs between $15 and $25 each way. For those looking for the ultimate priority, the Business Select fare automatically includes A1–A15 boarding. If you hold a Southwest Rapid Rewards Priority Credit Card, you may be eligible for up to four reimbursed Upgraded Boardings per year, making it a "free" perk for loyal travelers who want to skip the line and grab a front-row seat.
