Edinburgh – London Heathrow: how often flights are 3+ hours late or cancelled

Of 7,842 scheduled flights between Edinburgh and London Heathrow in 2025, 1.7% (95% range 1.4%–2.0%) were cancelled (120) or at least 3 hours late (about 13) — roughly 1 in 59. That is worse than 72% of 834 busy UK routes (median 1.1%). The route is 534 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.
