Southwest Airlines rolling out new fee for early boarding

MILWAUKEE (WITI) -- Southwest Airlines is rolling out a new fee for early boarding. 

It will now cost travelers $40 to be a part of Southwest's first boarding group.

The airline does not have assigned seating and lets passengers board in three groups. 

Currently, passengers can ensure they board first by buying a special business class ticket or joining a loyalty program.

Now, everyone will have that option if spots are available.

Passengers will be able to pay at the gate starting 45 minutes before a flight leaves.
