Planes registered in the United Kingdom have been banned at Russia’s airports and from crossing its airspace, Moscow’s aviation regulator announced.
Russia said the move was a response to “the unfriendly decisions by the UK aviation authorities”.
On Thursday, the UK banned Russia’s national airline Aeroflot from landing in Britain.
The measure was part of sanctions introduced following Moscow’s invasion of Ukraine.
Russia’s civil aviation authority Rosaviatsia said the measure was taken “as a response to unfriendly decisions by the UK aviation authorities regarding the restriction on regular flights of aircraft owned, leased or operated by a person associated with Russia or registered in Russia”.
British Airways said in a statement it was notifying customers on cancelled services and would offer full refunds.
“We apologise for the inconvenience but this is clearly a matter beyond our control,” the airline said.
British Airways normally operates three flights per week each way between London and Moscow.
Following Russia’s announcement, Virgin Atlantic also said flight paths had been adjusted for some of its services between the UK, Pakistan and India.
Virgin Atlantic apologised for the delays, adding: “The safety and security of our customers and people always comes first and we’re monitoring the situation in Ukraine and Russia extremely carefully following the escalation of conflict.”
Ukraine’s airspace closed on Thursday after Russian forces launched a military invasion of the country.
Moldova also said it was closing its airspace and Belarus shut part of its airspace on Thursday.
Polish Prime Minister Mateusz Morawiecki said on Friday that his government would also prepare a resolution which will result in closing Poland’s airspace for Russian airlines.
The European Union Aviation Safety Agency has warned of safety risks in flying in airspace near to Ukraine’s borders, including in Russia.
“There is a risk of both intentional targeting and misidentification of civil aircraft,” the regulator said on Thursday.
“The presence and possible use of a wide range of ground and airborne warfare systems poses a high risk for civil flights operating at all altitudes and flight levels.”
The US Federal Aviation Administration has also expanded the area where it says US airlines cannot operate in and near Ukraine.
