ATH→EWR

United Airlines flew 51% of the 1,218 flights between ATH and EWR in the DOT's count, with Emirates on 601. Loads averaged 252 passengers a flight, which on this route means wide-body aircraft nearly full.

The DOT's international report puts 150 flights on the pair in August 2025, the busiest month of the window, and 53 in February 2026, the thinnest. A summer-to-winter swing of that size means the winter schedule is a different operation: fewer frequencies, so a cancellation leaves a longer wait for the next seat.

EUROCONTROL's figures for Athens as a whole, every airline and every destination: 63.9% of departures and 66.5% of arrivals within 15 minutes of schedule from 1 January to 21 October 2026, with 94.5% of scheduled flights operated. The last seven days ran at 70.0% for departures, 6 points better than the year so far. Air traffic flow management delay attributed to the airport averaged 4.1 minutes per arriving flight this year, 4.3 over the last week.

Every US route from Athens, and its full punctuality record

Newark Liberty International is scored on this site from the DOT's domestic data: 77.4% of its 122,267 domestic departures arrived on time over the last twelve months, with delayed flights running a little over an hour late, and 3.44% were cancelled. Those are domestic flights, not this route, but an arriving transatlantic flight shares the same runways, the same weather and the same ground delay programmes, so a bad day at EWR reaches a flight from ATH just as surely. The airport's own page has the hour-by-hour and month-by-month detail, and its live FAA status appears above when the FAA has something to say.

Newark Liberty International (EWR) delay statistics, hour by hour and month by month

Every flight that departs Athens falls under Regulation (EC) 261/2004, whichever airline flies it and wherever it lands. If it arrives at Newark Liberty International three hours or more late, or is cancelled with under 14 days' notice, and the cause was within the airline's control, each passenger is owed €600 (€300 if the airline got you there under four hours late), on top of rebooking and care. Weather, air traffic control restrictions and strikes outside the airline are the usual exemptions. The return flight from EWR is covered only when the carrier is EU based. The sector is about 4,944 miles, 7,955 km, which puts it in the top distance band.

There is no grade to give ATH to EWR without a route record, and this site does not invent one. What the three sources support: about one departure a day in each direction, a choice of two carriers, a departure airport that gets 64% of its departures away on time and an arrival airport that runs 77% on time domestically. Leave two hours for any onward connection at EWR; immigration comes before the connecting flight.

Greece publishes no route-level punctuality, so this page cannot grade the route. The UK pages in this section can, because the CAA does.
