Southwest’s new premium seats are free for the rest of the year, you just have to find one.

Spirit Airlines announced on Tuesday that it will offer new premium options for its travelers, including an extra-legroom seating option and a two-free-checked-bags policy for its cardholders.

When you’re traveling alone and just don’t care. “It’s absolutely not worth it,” says Joanna Teljeur, a spokeswoman for AirAdvisor. Airlines may suggest that you won’t have a seat at all if you forego a seat assignment, but that’s a fake-out. You have a seat on the flight and you’ll get a seat assignment when you check in.
