Bristol has two weak spots: short flights to the Channel Islands and low cloud with fog. Otherwise, in 2025 the airport performed better than the national average (1.6%), largely thanks to easyJet UK: it operates half of all flights (34,339) with a share of just 0.9%.
Flights to Jersey and Guernsey
The worst route is Jersey: 8.0% across 709 flights, while Guernsey sits at 4.0%. Small island carriers fly these routes: Blue Islands at 8.8%, Aurigny at 4.0%. Jersey lies 245 km away, so the UK261 payout on such a flight is £220. The holiday routes tell the opposite story: Ibiza at 0.0%, and Jet2 at 0.4% with 3 cancellations.
Fog and low cloud
From January 2018 to September 2026, EUROCONTROL imposed a weather restriction on arrivals at Bristol on 57 days out of 3,189 (1.8%), most often in January and September (4% of days). Cancellations are not included in this figure. On those days, cloud dropped to 200 ft or lower in 68% of cases (compared with 21% on ordinary days), fog was present in 51% (against 11%), while strong wind barely stood out: gusts of 30 knots or more occurred 18% of the time versus 12%. The month-by-month breakdown is on the Bristol weather page.
