Delta Air Lines Adds New Route To Greece Advertisement: Delta Air Lines has announced new flights to Greece from its largest hub in Atlanta. As the country reopens for tourism, whether passengers are vaccinated or not, Delta will fly to Athens from two hubs this summer. The first flights to Greece will start in May, as Greece is one of the few spots in Europe open for American tourists. Delta will use Airbus A330-300 aircraft to connect two hubs, New York and Atlanta, to Greece this summer.
