Icelandair at Glasgow: how often flights are 3+ hours late or cancelled

Of 683 scheduled Icelandair flights to and from Glasgow in 2025, 1.2% (95% range 0.6%–2.3%) were cancelled (7) or at least 3 hours late (about 1). Other airlines at Glasgow: 2.2%; the 95% ranges overlap, so the difference may be chance. Icelandair at all UK airports: 1.5%. Compensation under UK261 is due only when the airline is at fault, so this is an upper estimate. Source: UK CAA.

Caveats

This is an upper estimate of flights where compensation may be due. Weather, air traffic control, strikes by third parties and security problems are “extraordinary circumstances” and give no right to compensation; cancellations announced 14 days or more ahead do not either.
The CAA measures delay at the UK airport (departure or arrival). The legal test is the delay on arrival at the final destination.
Flights in both directions are combined. For flights from an EU airport, EU261 applies when the airline is an EU airline (€250 / €400 / €600), UK261 when it is a UK airline.
