S7 Airlines was seen as a Russian success story less than two months ago. The country was connected to western Europe, Central Asia, and even Thailand by the carrier. A member of the Oneworld global aviation alliance that also includes British Airways and American Airlines, S7 boasted a solid safety record, paid its bills on time, and had a charismatic leader who created the nation.

The airline he built is stuck between international sanctions and a Russian government that is determined to keep its aviation industry aloft. The airline, which used to offer service to 35 nations, is cut off from both overseas destinations and the flow of aircraft maintenance essentials that are key to keeping a modern airline running.
