Russia's largest private airline S7 Group said on Wednesday that it was putting plans to launch a low-cost carrier on hold after aircraft deliveries were cancelled.
The company said last July that it planned to launch "Citrus", a budget airline focusing on regional routes.
"In 2022 deliveries of the aircraft required to launch the low-cost airline will not take place, so the development of the airline with this business model is unfortunately not possible now," the airline said in a statement.
It said it would make a decision on the future of the project by the end of the year.
Western sanctions over Moscow's military campaign in Ukraine have triggered a crisis in Russia's aviation sector, which has seen flights to Europe and the United States cancelled and the use of foreign-made aircraft restricted.
