Why are these airports at risk?
- Bolzano (BZO) and other alpine airports like Lugano (LUG) often suffer from adverse summer weather conditions such as sudden thunderstorms and capricious winds that can affect flight safety and regularity.
- Brno (BRQ) and some medium-sized airports face increasing pressure on air traffic, with limited ATC capacity and possible delays in managing growing traffic.
- Toulon-Hyères (TLN) and airports in southern Europe report rising summer traffic loads, occasional strikes by ground staff or air traffic control, as well as hot weather with afternoon thunderstorms.
Top 10 Most At-Risk Routes
The routes with the highest risk of disruptions are mainly connected to London Stansted (STN) and London Luton (LTN), likely due to heavy traffic and ongoing issues with UK ATC.
- AGP (Málaga) -> LTN (Luton): 43.2
- PMI (Palma de Mallorca) -> LTN (Luton): 43.2
- DUB (Dublin) -> STN (Stansted): 43.0
- CDG (Paris Charles de Gaulle) -> LTN (Luton): 42.9
- ALC (Alicante) -> LTN (Luton): 42.7
- BCN (Barcelona) -> LTN (Luton): 42.7
- ZRH (Zurich) -> LTN (Luton): 42.7
- AMS (Amsterdam) -> STN (Stansted): 42.6
- NCE (Nice) -> STN (Stansted): 42.6
- CPH (Copenhagen) -> STN (Stansted): 42.4
Main reasons:
- Air congestion around London remains a critical factor due to both infrastructure limits and high summer traffic volumes.
- Possible strikes by UK ATC staff and internal logistical issues with low-cost carriers dominating these routes can cause significant impacts.
Practical Tips for Travelers
