The Atlanta to Miami route covers roughly 600 miles and takes about 1h 55m nonstop. 4 airlines compete on it — Delta Air Lines, American Airlines, Southwest Airlines, Frontier Airlines — which keeps fares moving and makes it worth comparing carriers rather than defaulting to the one you usually fly. We have seen one-way fares on this route start around $78.
Miami runs on three things: the water, the food, and the night. South Beach supplies the Art Deco skyline and the sand, Little Havana supplies the cafecito and the domino tables, and Wynwood supplies the murals and the galleries.
It is also the most connected gateway in the United States to Latin America and the Caribbean, which is why fares here move so much with the seasons — winter is peak, late summer is a bargain.
