Just playing around on Frontiers website and noticed fares just dropped. I am non-reving CAK-DEN on March 7th, and returning on March 9th. My zed non-rev fare is $106, and the current fare is $189. That makes it very tempting to just buy the ticket and not worry, but there appears to be a lot of empty seats on these flights right now. Any chance someone could shed some light on the actual bookings so I can make an informed decision?
