Q. My wife and I are flying Southwest and have purchased the option for EarlyBird check-in. What exactly is required to early board with Southwest?
A. Boarding positions for EarlyBird passengers are assigned in the order they are purchased, so the earlier you buy, the better your position in the queue. However, passengers who have purchased Anytime Fares and Business Select do take priority over EarlyBird buyers. That means you might not necessarily get an A boarding position, but you'll still be among the first to choose seats.
You can access your boarding passes and check-in 24-hours before your scheduled departure time, though this will have no bearing on your boarding position.
