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

Of 1,980 scheduled flights between London Heathrow and Bologna in 2025, 1.3% (95% range 0.9%–1.9%) were cancelled (21) or at least 3 hours late (about 5) — roughly 1 in 76. That is worse than 57% of 834 busy UK routes (median 1.1%). The route is 1,163 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.
