In Birmingham in 2025, the airline and the route decided a flight's fate; weather barely got involved. The airport as a whole is slightly more reliable than the national average (1.6%), but the spread within it is wide: from fractions of a per cent among the low-cost carriers to 7.3% for Air India.
Which airline and which route
Ryanair had 0.6% of flights disrupted and Jet2 0.7%. At the other end sits Aer Lingus: 258 cancellations out of 7,587 flights, 4.0%, with regional carrier Loganair close behind (3.9%). The short routes fare worst: Belfast City 4.9%, Guernsey 4.4%. The busiest route, Dublin, comes in at 1.9% across 7,515 flights, while Las Palmas is just 0.1%. UK261 compensation in the route table: £220 on routes up to 1,500 km and £350 to Las Palmas (2,951 km).
Why weather has almost nothing to do with it
Between January 2018 and September 2026, EUROCONTROL imposed weather restrictions on arrivals at Birmingham on just 13 days out of 3,195 (0.4%). That figure excludes cancellations and covers only restrictions on arrivals, but even so it is clear that disruptions here are rarely down to the weather.
