What you have found on TAROM's website are the possible flight combinations with departure point at OTP, using TAROM flights PLUS some other airlines' flights, airlines that signed agreements with TAROM; e.g.: OTP - YUL  (Bucharest OTP - Montreal Dorval) route, operated by TAROM on OTP - LHR (London Heathrow) one stop in London and Air Canada's LHR - YUL flight. This cannot be counted as a TAROM's international destinaton, because it is not a DIRECT Bucharest - Montreal flight and it is not operated by a TAROM aircraft on all its length. On the other hand, OTP - LHR (Bucharest - London) can be counted as an international destination for TAROM. It is a direct flight, operated by a TAROM aircraft.
