EU ruling creates uncertainty regarding flights between Dublin and Spain
The European Court of Justice ruled that 'grandfathered slots' for airlines are not absolute and can be restricted in cases of insufficient capacity. This affects airlines like Ryanair and Aer Lingus operating flights between Dublin and Spain. The ruling creates uncertainty about future flight frequencies, despite no immediate impact on current bookings. Ryanair seeks to remove passenger limits, while the Irish government plans to review capacity by 2026.
