London Gatwick – Tunis: how often flights are 3+ hours late or cancelled

Of 708 scheduled flights between London Gatwick and Tunis in 2025, 4.1% (95% range 2.9%–5.8%) were cancelled (0) or at least 3 hours late (about 29) — roughly 1 in 24. That is worse than 94% of 834 busy UK routes (median 1.1%). The route is 1,791 km, so when the airline is at fault UK261 compensation is £350 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: 1,791 km

Distance	Delay at arrival	UK261 compensation
1,791 km	3 hours or more, or a cancellation less than 14 days ahead	£350 per passenger

Weather is a frequent reason why no compensation is due: at London Gatwick EUROCONTROL restricted arrivals for weather on 17% 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.
