I wanted to create a new thread since burying this in the "New Frontier Website" thread might hide this from new viewers who don't want to read through all those old posts. Anyway, Frontier has unveiled a new domain and features designed to drive bookings through the website:
http://www.flyfrontier.com/
They've introduced some "penalties" to fliers that book elsewhere, like not being able to choose seats and only earning 50% mileage. Also, they've lowered their award tiers (EarlyReturns makes sense again!) to 10k miles (o/w) and 20k (r/t) but removed the free checked bags. You can see those here:
