Yes, you can fly from Alaska to Russia. The Bering Strait separates the two by only ~85 miles (137 km) at its narrowest. Commercial airlines operate direct flights between Anchorage (ANC) and Petropavlovsk-Kamchatsky (PKC), taking about 5.5 hours. Seasonal and charter flights may also connect other Alaskan communities (e.g., Nome) with Russian Far East destinations. Note that visas and border regulations apply.
