Keflavík had 12,600 flights to and from the United States in the twelve months to June 2026, about 17 departures a day in each direction spread over 16 US routes, the busiest being New York (JFK) with 1,713. EUROCONTROL has 69.0% of all its departures leaving within 15 minutes of schedule this year and 77.8% of arrivals landing within 15 minutes, from about 86 departures a day; on arrival punctuality that is 15th of the 41 European airports here with US service. Iceland publishes no route-level punctuality, so the US routes below are described by frequency and carrier rather than by delay.

On departure punctuality Keflavík stands 28th of 41: Stockholm Arlanda leads at 84.0% and Lisbon trails at 57.5%. By transatlantic volume it is 9th 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 Keflavík is running

Over the seven days to 21 October 2026, 70.5% of departures and 78.1% of arrivals were within 15 minutes, 2 points better than the year to date. 88.5% 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 0.0 per arrival this year and 0.0 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.
