Yesterday, the EU adopted an amendment to the Slot Regulation that relieves airlines of airport slot-use requirements for the summer 2021 scheduling season. This amendment replaces the current full slot waiver, which is no longer justified for the next season. It allows airlines to return up to half of the airport slots that they have been allocated before the start of the season. They are then required to use at least 50% of their remaining slots in order to retain the rights of those slots for future years. If routes are affected by measures adopted in the context of COVID-19, airlines may be exempted from this 50% threshold without losing their rights to these slots.
