London Heathrow – Dundee: how often flights are 3+ hours late or cancelled
Of 907 scheduled flights between London Heathrow and Dundee in 2025, 3.2% (95% range 2.2%–4.5%) were cancelled (27) or at least 3 hours late (about 2) — roughly 1 in 31. That is worse than 91% of 834 busy UK routes (median 1.1%). The route is 579 km, so when the airline is at fault UK261 compensation is £220 per passenger. This is an upper estimate: weather and air traffic control problems give no right to compensation. Source: UK CAA.

Weather is a frequent reason why no compensation is due: at London Heathrow EUROCONTROL restricted arrivals for weather on 32% of days in 2018–2026.
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.
