The Russian airline Aeroflot currently has three A320 series aircraft "stuck" in the European Union and Switzerland. Due to the airspace closure for Russian airlines, these are not allowed to leave the respective airports until further notice.
The Airbus A320 with the registration VP-BET is stranded in Munich, Germany. This flew in from St. Petersburg on Sunday and was unable to leave the Bavarian airport due to the flight ban imposed on Russian airlines by the German government.
The Airbus A320 with the registration VP-BAC is stuck in Amsterdam. This was on the way from Moscow Sheremetyevo to Düsseldorf on Sunday. The carrier did not reach the planned destination due to the airspace closure and therefore had to switch to Amsterdam. You can no longer leave this airport because of the EU-wide ban.
The Airbus A321 with the registration VP-BOE is stuck in Geneva, Switzerland. This came from Moscow Sheremetyevo. It was no longer possible to take the route via Germany because the airspace was closed. They then wanted to fly to Mineralnyje Vody via France and Italy, but nothing came of it because the two countries also closed their airspaces to Russian carriers.
