The only direct flights into Moldova are from Berlin and Paris. A better option is to fly to Bucharest and then take a bus or train to Chisinau. Buses can also be taken from Suceava in Romania to Chisinau. Trains from Bucharest are probably the best way to go, as they are the most economical. There are, however, no discount fares or rail passes available.
Buses also run between most of the larger towns and cities.
