While the travel industry assesses the shock of the COVID-19 pandemic and a near halt to domestic and international travel, airlines throughout the world are re-working their schedules to adapt to a new reality — at least for the next several months.

United Airlines has already announced the suspension of its non-stop service from Newark Liberty International Airport to Athens for the entire 2020 season. The Chicago-based airline operated a daily flight to the Greek capital from May until October, since 2016.

American Airlines has also axed its daily non-stop service from Philadelphia to Athens. The airline announced that its daily non-stop service between Chicago and Athens would resume on June 5.

Emirates, which also flies year-round daily service between Newark and Athens, stopped operating most of its flights in March. The company recently announced a resumption of service, including the Athens route, on July 1.
