Hello there, I had low expectations about Frontier Airlines ATL Terminal but was rather impressed. The terminal was neater than expected, with simple boarding zones and friendly staff. Self-service stations ensured check-in was quick, but I found the bag drop lines to be quite long—get there early just in case. There's not much by way of food options around the area, though there are a few good coffee places. Security was uneventful, and there was sufficient room in the gate area to wait before boarding. In general, if you understand Frontier's approach—low price, no frills—you'll be good. The Airlines terminal reinforces that attitude: streamlined, no-frills, and it works.
