One week ago the British government announced sanctions against three Russian airlines: Aeroflot, Ural Airlines and Rossiya Airlines. This kept them from selling or leasing takeoff and landing slots at U.K. airports. Russian airlines already couldn’t enter U.K. airspace.
We now know what this means in practice for their London Heathrow slots: Russian airlines don’t just lose the ability to profit from their slots, they actually lose the slots.
