These Regulations amend retained EU law in the field of aviation, relating to the allocation of slots at congested airports. They amend Council Regulation (EEC) No 95/93 of 18 January 1993 on common rules for the allocation of slots at United Kingdom airports (“Regulation 95/93”), to make provision about the allocation of airport slots to air carriers in respect of a specified period, following a reduction in the level of air traffic as a result of COVID-19.
