Southwest Airlines unveiled new fare bundles this week, giving fliers a first look at how different fares will determine seat selection, checked bag charges, refunds and more.  The new bundles are a shift from the usual tickets that range from the cheapest Wanna Get Away fares to the more luxurious Business Select fares.

The most expensive bundle in Southwest's new fare program will be Choice Extra, which will also include the most add-ons as part of the base fare. Choice Extra ticketholders will get early boarding, two free checked bags and complimentary access to extra legroom seats at booking and complimentary internet.
