The best deal by far is to credit your rental car miles to Southwest. You get a half credit per rental (though Alamo is currently offering 1 full credit!), which means you get a free flight in 32 rentals.

Do you have to fly Southwest to get the credit. I mean do they require some proof of travel on Southwest within certain period of the rental?
