The restrictions say emergency landings or overflight are allowed (at least the European restrictions on Russian flights that I read; I assume the American and Russian restrictions are similar). However, an EU/US flight landing in Russia might have problems importing any required spare parts to fix the plane [1]. Russian planes making an emergency landing in the EU/US had better be owned by their airlines, rather than leased, or they're likely to be seized.
