The increase of SSJ100 flights is based on the most recent schedule file, which was submitted over the weekend. There are currently 70,376 services, up 15% (and 9,203) in only one week. It's also the first time the number of monthly flights has surpassed 10,000, with over 14,000 total.
The twin-engine aircraft has never performed nearly as many services. The rise shows that it is due in part to the current circumstances.
A large number of aeroplanes registered in Ireland will be repatriated. At the same time, the Bermuda CAA has revoked all Bermuda-registered aircraft's certificates of airworthiness in Russia. Multiple aircraft have been reregistered on the Russian (RA-) registry in the last few days as a result of this.
Boeing, Airbus, Embraer, and other aircraft manufacturers have ceased to offer parts and assistance to Russian operators. Even before Bermuda and Embraer announced the modifications, it was clear that they would have a significant impact on Russian airline operations.
However, changing the SSJ100's use may not be as simple, and not simply because the plane employs numerous Western components. Planespotters.net reports that 17 aircraft have been delivered since November and 76 since the beginning of 2021. Rossiya has been the principal receiver. Almost all of these planes are in the air.
According to the most recent filing, the increase in flights is due to Rossiya, which runs Aeroflot's planes. It had booked 24,929 SSJ100 flights between March and August as of last week. That number has now climbed by 35% to 33,573.
