Today we're announcing that ExpertFlyer now has a Paid Seat designation in it's Seat Maps. This designation will be used for any seat that is marked as a seat where a traveler would have to pay to reserve it by the airline. Since airlines can also mark such seats as free for elite frequent flyers as well as Paid, a second seat designation, Paid & Premium, as also been added. When you see this icon on a seat it means that the seat can be reserved by an elite frequent flyer, or by paying. ExpertFlyer previously shows these seats as Premium Only. For Seat Alerts, the "Paid & Premium" seat will be treated the same as a Premium Only seat. Paid seats will be treated as not available. To our knowledge, only WestJet and Frontier shows seats as Paid only, if you find others please let us know.
