Once I got past security, I looked around [[ https://airlinesairportsterminals.com/frontier-airlines/den-terminal-denver-international-airport/ | Frontier Airlines Denver Airport Terminal ]] facilities and services. Food options in the terminal ranged from sit-down restaurants to quick grab-and-go meals. I liked the inexpensive dining alternatives because I was on a tight budget, but those who wanted a more upscale experience could also choose from more expensive options. Throughout the concourse were retail stores that sold travel necessities, souvenirs, and food.
