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

Of 720 scheduled flights between London Heathrow and Kigali in 2025, 8.5% (95% range 6.7%–11%) were cancelled (12) or at least 3 hours late (about 49) — roughly 1 in 12. That is worse than 99% of 834 busy UK routes (median 1.1%). The route is 6,605 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.
