"The Russian Federal Air Transport Authority has warned airlines that changing flight routes bypassing Belarus may take longer than usual due to the large number of requests." RBK reports it on Twitter.
Cases of refusal by the Russian authorities to authorize flights from the EU flying around the territory of Belarus are caused by "technical issues" of coordination of entry points into Russian airspace. This was stated by the spokesman of the Kremlin, Dmitry Peskov, quoted by the TASS.
"The Russian authorities today issued a permit to Austrian Airlines for an alternative flight route from Vienna to Moscow, which does not pass through Belarusian airspace. Therefore Austrian Airlines can perform scheduled flight OS 601/602 from Vienna to Moscow and I'm back today, "said the airline representative who was forced to cancel the flight yesterday.
The ban by "Western countries" to allow flights to "cross Belarusian airspace for political reasons is irresponsible and jeopardizes the safety of passengers". This was stated by the spokeswoman of the Russian Foreign Ministry Maria Zakharova, commenting on the decision to avoid Belarusian space after Sunday a Ryanair plane flying from Athens to Vilnius was landed in Minsk due to an unfounded bomb alert, while the journalist was arrested Roman Protasevich who was on board.
