We are flying to Cancun from CVG with two four year olds. Since the flight is now scheduled at 6:00 am we will be staying nearby at the Doubletree where they have a 24/7 shuttle. We have a couple of questions;

Where are the Frontier counter and gates at CVG?

How early do we need to be at the airport?

Is there any place to buy food at 5 am at CVG near the Frontier counter or gates?

Is breakfast served on that flight?
