Porto had 1,780 flights to and from the United States in the twelve months to June 2026, about two departures a day in each direction spread over 2 US routes, the busiest being Newark (EWR) with 1,480. EUROCONTROL has 74.2% of all its departures leaving within 15 minutes of schedule this year and 75.2% of arrivals landing within 15 minutes, from about 167 departures a day; on arrival punctuality that is 30th of the 41 European airports here with US service. Portugal publishes no route-level punctuality, so the US routes below are described by frequency and carrier rather than by delay.
On departure punctuality Porto stands 13th of 41: Stockholm Arlanda leads at 84.0% and Lisbon trails at 57.5%. By transatlantic volume it is 28th of the 45 European airports with a page here; London Heathrow leads with 81,419 flights. Punctuality and volume do not move together: a hub's transatlantic bank is scheduled around its own connecting flights, and the arrivals that feed it are where the delay comes in.

Punctuality
How Porto is running
Over the seven days to 21 October 2026, 68.0% of departures and 70.7% of arrivals were within 15 minutes, 6 points worse than the year to date. 96.9% of scheduled flights have operated this year, the remainder cancelled or never filed. Air traffic flow management delay charged to the airport, the minutes the network held flights on the ground elsewhere to protect it, averaged 1.2 per arrival this year and 3.5 over the last week. These are whole-airport figures from EUROCONTROL's Network Manager, published daily and refreshed here with each build; the long-haul bank usually runs a little better than the airport average because wide-body schedules carry more slack.
| Window | Departures on time | Arrivals on time | Schedules operated | ATFM delay / arrival |
|---|---|---|---|---|
| Yesterday (21 October 2026) | 78.8% | 83.5% | 95.6% | 0.0 min |
| Last 7 days | 68.0% | 70.7% | 96.5% | 3.5 min |
