I just flew Frontier Airlines CVG Terminal Overall, my experience was great. Terminal easy to navigate with great signage. Check-in process was fast. Security check-in was fast as well with little wait. Seats were simple, but it was enough for the waiting period. Food selection is very limited, but they were not overpriced. Boarding was pretty easy, and the staff are friendly. In general, the experience was seamless at CVG, and I would definitely fly out of this facility again with Frontier.
