London City – Zurich: how often flights are 3+ hours late or cancelled

Of 4,022 scheduled flights between London City and Zurich in 2025, 1.4% (95% range 1.1%–1.9%) were cancelled (55) or at least 3 hours late (about 3) — roughly 1 in 69. That is worse than 64% of 834 busy UK routes (median 1.1%). The route is 760 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.

The 95% ranges of at least two airlines do not overlap, so the difference between them is unlikely to be chance. Airlines with at least 100 scheduled flights on the route; operating companies are shown as the CAA lists them (for example easyJet UK and easyJet Europe), because that decides whether UK261 or EU261 applies.

What you may be owed

UK261 compensation by great-circle distance; this route: 760 km

Distance	Delay at arrival	UK261 compensation
760 km	3 hours or more, or a cancellation less than 14 days ahead	£220 per passenger

Weather is a frequent reason why no compensation is due: at Zürich EUROCONTROL restricted arrivals for weather on 33% 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.
