• Ryanair to stop flights to and from the Azores.
• High airport fees imposed by ANA.
• Airline criticized Portuguese government's inaction.
• 120% rise in air traffic control fees since pandemic.
• EU's ETS applies to flights within Europe, but not to long-haul flights to US and Middle East

This decision may indicate Ryanair's willingness to re-evaluate its operations in response to regulatory challenges. The airline's criticism of the Portuguese government's inaction suggests a broader concern about the impact of EU regulations on low-cost carriers. The EU's ETS expansion to the Azores may also highlight the need for more nuanced approaches to environmental policies and their effects on regional connectivity.
