I was pleasantly surprised with the Frontier Airlines Denver Airport Terminal. The airline employees ensured that passengers were boarding in a systematic manner, and the structure was easy to understand. The gate agent was really kind and knowledgeable when I had queries concerning my carry-on. The restrooms were spotless, and while I waited for my flight, I could even peruse a few neighboring stores with Colorado themes.
