No public record scores Shannon to Newark Liberty International flight by flight. The US Department of Transportation's on-time database covers domestic flights only, and in Europe only the United Kingdom publishes punctuality by route, so what follows is built from the three measurements that do exist. The DOT's international report counts 408 flights between the two airports in the twelve months to June 2026, about four departures a week in each direction, flown by United. EUROCONTROL publishes no punctuality series for Shannon. At the other end, 77.4% of EWR's domestic departures arrived on time in the DOT data, which says something about how the airport itself runs, not about this route.
EUROCONTROL does not publish a punctuality series for Shannon, so the departure end of this route cannot be ranked against other European gateways here.

US DOT, last twelve months of domestic departures
Without a route-level record, the useful question is what the two airports do to a schedule. In the DOT data, a delayed domestic departure from EWR ran a little over an hour late on average over the last twelve months, and 3.44% of its scheduled flights were cancelled.
Carrier by carrier
Who flies SNN to EWR
United Airlines is the only carrier the DOT report shows on SNN to EWR, with 408 flights and an average of 148 passengers aboard each. A single-carrier route gives a delayed passenger no same-day alternative on the same ticket, which is worth knowing before booking a tight onward connection.

DOT international report, July 2025 to June 2026; flights in both directions together. No delay figures exist for this pair in any public source.
Across the year
How often SNN to EWR flies through the year
The DOT's international report puts 62 flights on the pair in August 2025, the busiest month of the window, and 0 in March 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.

The arrival airport
Landing at Newark Liberty International
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 SNN 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.

Your rights
EC 261/2004 on SNN to EWR
Every flight that departs Shannon 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 3,087 miles, 4,967 km, which puts it in the top distance band.

What to do with this
Booking SNN to EWR
There is no grade to give SNN to EWR without a route record, and this site does not invent one. What the three sources support: about four departures a week in each direction, a single carrier, a departure airport that EUROCONTROL does not score 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.
