Transnistrians are able to travel (normally without difficulty) in and out of the territory under PMR control to neighbouring Moldovan-controlled territory, to Ukraine, and on to Russia, by road or (when service is not interrupted by political tensions) on two international trains, the year-round Moscow-Chișinău, and the seasonal Saratov-Varna. International air travellers rely on the airport in Chișinău, the Moldovan capital, or the airport in Odessa, in Ukraine.
