Hartsfield-Jackson International is a top ranked U.S. airport for transit access, according to a new survey.

The survey released by the Global Gateway Alliance showed that Atlanta’s airport is one of the best worldwide for mass transit access. The Global Gateway Alliance, a nonprofit created to address airport infrastructure issues in the New York area, ranked the world’s 30 busiest airports for passenger traffic based on mass transit travel time, cost, mode and transfers.

The Atlanta airport trailed only Madrid, Amsterdam, Dubai and Frankfurt airports, making it the top ranked U.S. airport in the survey.

MARTA takes passengers directly into the domestic terminal at Hartsfield-Jackson — however, MARTA does not reach the airport’s international terminal. MARTA riders generally must take a shuttle bus to get from the domestic terminal to the international terminal on the other side of the airport.

Ranking lowest for mass transit access in the survey were New York’s John F. Kennedy International and Denver International airports.
