OBS_VALUE: Slots are allocated from the slot pool to applicant carriers. The slot pool is made by a coordinator and it excludes those slots that are retained from one season to the next subject to the condition that the slots are operated for at least 80% of the time for which they were allocated.Due to the COVID-19 pandemic, coordinators shall consider slots allocated for the period from 1 March 2020 until 27 March 2021 as having been operated by the air carrier to which they were initially allocated. The same already applied for the period from 23 January 2020 until 29 February 2020. For the slots allocated for the scheduling period from 28 March 2021 until 30 October 2021 air carriers are entitled to the same series of slots for the scheduling period from 27 March 2022 until 29 October 2022 if the air carrier has made the complete series of slots available to the coordinator for reallocation before 28 February 2021. In December 2021, the Commission adopted a further extension to the slot relief rules to cover the 2022 summer scheduling season, running from 28 March 2022 until 29 October 2022. During this period, instead of the normal requirement to use at least 80% of a given slot series, airlines only have to use 64% to retain the same series of slots for the next equivalent scheduling period.
