Edinburgh – Washington Dulles: how often flights are 3+ hours late or cancelled

Of 517 scheduled flights between Edinburgh and Washington Dulles in 2025, 4.6% (95% range 3.1%–6.8%) were cancelled (12) or at least 3 hours late (about 12) — roughly 1 in 22. That is worse than 96% of 834 busy UK routes (median 1.1%). The route is 5,581 km, so when the airline is at fault UK261 compensation is £520 per passenger. This is an upper estimate: weather and air traffic control problems give no right to compensation. Source: UK CAA.
