The UK government has introduced sanctions against Russian state-owned Aeroflot, the country’s largest airline, plus Ural Airlines and Rossiya Airlines.
All three will be unable to sell unused landing slots at Heathrow and Gatwick.
Foreign Secretary Liz Truss said: “As long as Putin continues his barbarous assault on Ukraine, we will continue to target the Russian economy. We’ve already closed our airspace to Russian airlines. Today we’re making sure they can’t cash in their lucrative landing slots at our airports. Every economic sanction reinforces our clear message to Putin – we will not stop until Ukraine prevails.”
