Effective August 29, Southwest Airlines will be increasing its fees for EarlyBird check-in (the option where travelers purchase the ability for a better boarding position in Southwest's open seating system) on some flights.
The new EarlyBird check-in fee ($20 or $25 each way) is determined by both the length of the flight and the historical popularity of EarlyBird check-in on the route. On flights where one of the new fees is not applicable, the existing $15 fee each way will continue to be assessed.
