competence of the European Aviation Safety Agency (EASA) is to be extended to aerodromes, air traffic management and air navigation services. The 'action plan for airport capacity, efficiency and safety' is to be implemented thus providing ground capacity. The SES-II aimed to merge 36 national airspaces into 9 Functional Airspace Block (FABs) in order to provide better performance, ultimately 3 years later on 4 December 2012. The air travel disruption after the 2010 Eyjafjallajökull eruption caused an acceleration to merge member states' air traffic control systems into the Single European Sky, and the immediate creation of a crisis co-ordination group to handle future transport disruptions. On 2 December 2010, France, Germany, Switzerland and the Benelux countries agreed to form the FABEC (Functional Airspace Block Europe Central), the third FAB to be created after the Dano-Swedish and Anglo-Irish block. The FABs were supposed to enter into effect by 2012, but delays were expected due to protests from ATC labour unions. The FAB CE, consisting of Austria, Slovenia, the Czech Republic, Slovakia, Hungary, Croatia and Bosnia-Herzegovina, was formed in 2011. By 26 October 2012, only the Anglo-Irish and Dano-Swedish FABs had been fully implemented, while the other 7 FABs were still in various stages of development; the deadline for the full realisation of the Single European Sky on 4 December 2012 was missed. SES 2+ (2013–2018) On 10 June 2013, the European Commission presented its plan "B" to speed up the implementation process of SES. The so-called SES 2+ is a package of measure which aim at challenging the current situation with state owned monopolies responsible for providing air navigation services. At the same time, transport workers' union ETF announced mobilising its members to protest against the suggested package. Negotiations on SES 2+ stalled in the Council in 2015. In 2017, the European Court of Auditors determined that the functional airspace blocks have failed to defragment European airspace as they have not been fully implemented, with aircraft still being serviced by a different air navigation provider in each member state with different rules and requirements. This was due to a "lack of commitment on the part of the member states". Amended SES 2+ (2019–present) By 2019, nothing of the plan had yet been officially realised, adding an extra 6 billion euros in costs, and 11.6 million megatonnes of excess emissions for that year alone. In September 2019, 21 aviation organisations including Airlines
