Which rules cover PHL–ATH
Philadelphia → Athens
Whatever the airline, this direction is covered by US DOT (the flight departs from the United States (14 CFR 260.2, "covered flight")). On an EU airline it is also under EU261. On a UK airline it is also under UK261. If the airline refuses, the complaint goes to the US DOT for the refund, Hellenic Civil Aviation Authority for EU261 (the flight arrives in Greece from outside the EU) or the airline's dispute scheme or the UK CAA for UK261.
Athens → Philadelphia
Whatever the airline, this direction is covered by EU261 (the flight departs from the EU (Article 3(1)(a)), whatever the airline) and US DOT (the flight arrives in the United States (14 CFR 260.2, "covered flight")). If the airline refuses, the complaint goes to Hellenic Civil Aviation Authority for EU261 (the flight leaves Greece) or the US DOT for the refund.
Because both EU and UK rules can reach this route, a passenger may find two rules covering the same trip. Each excludes people already compensated under the other's law for the same event, so the claim is made once, under whichever the airline accepts — in money terms €600 or £520.
What you could be owed by hours late
Arrival delay at ATH (or PHL on the return), for a delay caused by the airline, per passenger, where each rule applies:
| Hours late | EU261 | UK261 | US DOT |
|---|---|---|---|
| 2 hours | €0 | £0 | Nothing |
| 3 h 30 min | €300 | £260 | Nothing |
| 4 h 30 min | €600 | £520 | Nothing |
| 6 h 30 min | €600 | £520 | Refund if you decline |
| 9 h 30 min | €600 | £520 | Refund if you decline |
At 8,083 km this is a long-haul flight, so the first hour of compensation is reduced: arriving 3 to 4 hours late pays €300 or £260, and the full €600/£520 starts at 4 hours. The US column is the refund right only: an international itinerary needs 6+ hours.
How Philadelphia PHL runs
In June 2026, 75% of reporting airlines' flights arriving at Philadelphia International Airport and 72% of those departing were on time (within 15 minutes), against 72.9% and 70.7% across the 30 largest US airports, according to the US DOT's Air Travel Consumer Report. Arrivals here ran at or above that average. The figures cover all reported flights at the airport, mostly domestic, not this route alone.
The distance and the band
EU261 and UK261 measure distance "by the great circle route method" between the departure airport and the final destination. From the published coordinates of Philadelphia International Airport (39.871899, -75.241096) and Athens Eleftherios Venizelos International Airport (37.936401, 23.9445) that is 8,083 km. The nearest band boundary is 3,500 km, 4,583 km below this route, so the band is not in doubt. Among the 148 routes on this site in the over 3,500 km band, it is number 19 by length.
Other routes from Philadelphia International Airport (KPHL) on this site: London (5,690 km), Dublin (5,253 km), Paris (5,984 km), Barcelona (6,300 km), Rome (7,017 km).
Other routes from Athens Eleftherios Venizelos International Airport (LGAV) on this site: London (2,427 km), Rome (1,085 km), Paris (2,109 km), New York (7,932 km), Newark (7,956 km), Amsterdam (2,182 km), Frankfurt (1,816 km), Munich (1,518 km), Santorini (218 km), Mykonos (136 km), Heraklion (309 km), Vienna (1,279 km).
If PHL–ATH is only one leg of your booking, measure to the final destination instead: a connection that makes you late at the end is compensated over the whole journey's distance.
If the flight is cancelled
Cancelled with less than 14 days' notice and re-routed to arrive 6 hours late, an EU261 passenger is owed €600 here. If the replacement left within the allowed early margin and landed within the re-routing window, nothing is owed; if it landed within 4 hours but outside those windows, the airline may pay half — €300. On a cancellation you may instead take a refund within 7 days.
Help at the airport while you wait
On a flight of this length, meals and refreshments are owed once the departure is 4 hours late under EU261 and UK261, and a hotel with transport if you have to stay overnight — whatever caused the delay. US law sets no meal or hotel duty; the large US airlines' published commitments do, and they are on the airline pages. Keep receipts for anything you buy: it is claimed back separately from any compensation.
Claiming on this route
Claim from the operating airline directly — it costs nothing.

EU261: If the airline does not reply within two months, or the reply is unsatisfactory, complain to the national enforcement body of the country where the incident happened.
