On 23 July 2021, the European Commission proposed to amend the Slot Regulation and extended the slot relief rules adopted in February 2021. As the aviation industry starts to recover from the impact of the COVID-19 crisis, the Commission remains committed to continuing relief from normal slot allocation rules for airlines. Relief will therefore be extended to the coming winter scheduling season, running from 31 October 2021 until 27 March 2022. Instead of the normal requirement to use at least 80% of a given slot series to retain historic rights in those slots, airlines will only have to use 50% of a given slot series.
