Frontier touts the new charge as the "more room" pledge. "While we believe the best measure to keep everyone healthy is to require face coverings, for those who want an empty seat next to them for extra peace of mind or simply additional comfort, we are now offering 'More Room,'" Frontier CEO Barry Biffle said in a written statement.
The extra fee for a guaranteed empty middle seat will be between $39 and $89, depending on the route.
