Southwest Airlines increases early bird check-in price on some flights

Southwest Airlines is raising the price on some flights for its early bird check-ins.
Starting next Wednesday, early bird check-ins will cost $15, $20 or $25 on some flights, instead of the current $15 per person flat rate.
The new price will depend on the length and popularity of the flight.
Early bird gives travelers a better boarding position in Southwest's open seating system.
The service started back in 2009 and cost $10.
