You can add bans to fly to or over most of Europe, likely Russian-imposed restrictions or total ban on flights leaving Russia and most of the parts supply chain refusing to serve them to the list of woes. Given the amount of flights they're currently unable to operate, losing some payment obligations to aircraft lessors may be almost be a relief. (The Russian government has threatened to "nationalise" some aircraft in retaliation, but the problem with doing that is you get your own aircraft repossessd when they leave Russia, even if trade with Russia reverts to near-normal after the war)
