I cant give you advice about the CO flight but I can give you info about the Frontier flight. First if your flight is an Airbus then direct tv will be offered (for a fee). The snack is a warm chocolate chip cookie and beverage. Other snacks are available for purchase along with some meal options and premium beverages. Now if you choose to go with frontier I would suggest you buy a Classic Plus ticket it allows for free checked bags, free tv, a free snack and premium beverage its a very good option.
