Is a 1¼ hr layover in Keflavik long enough?

Probably Enough
Plenty of buffer for KEF's compact layout, even during a busy transatlantic arrival bank.

AD PLACEMENT — CONTEXTUAL
Icelandair's whole schedule is built around tight transatlantic connections, so signage and staff are well-practiced at moving connecting passengers quickly — follow the 'Transfer' signs immediately on arrival.
If your itinerary crosses from a non-Schengen to a Schengen flight (or vice versa), budget extra time for passport control, which can have long lines during the morning arrival bank.
The terminal is small enough that even a 'gate change to the far end' rarely takes more than 10-12 minutes on foot.
Duty-free shopping fills the central corridor and can slow foot traffic during peak banks between 6-9am and 3-6pm.
PLAY and Icelandair use different check-in areas, so allow a few extra minutes if switching airlines rather than staying on one carrier's connection.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
There is no train or shuttle at KEF — the entire terminal is walkable, with the two concourses connected by a central hall of shops and lounges. Passengers transferring between a non-Schengen flight (e.g., North America) and another non-Schengen flight (e.g., UK) or a Schengen flight must pass through passport control and often a security re-screen, which is where most of the connection time is actually spent, not the walk itself.
Is 1 hour 15 min enough for a layover at KEF?
