Tarom has been a Boeing customer since 1974, when it took delivery of its first 707.
until 90's Tarom was the only Eastern European airline to own and operate an American made wide body jet.
The last civil build Boeing 707-300C, a cargo/passenger (Combi) variant with a large cargo door fitted to the forward port fuselage was delivered to TAROM in 1979

So I would agree that it must have been a thrill flying this 11 years old aircraft in the 90's on the OTP- AMS - JFK route. It was like the "Orient Express" version of the air travel.
But that's history now.
It appears that in the 90's Rumanian and Dutch Civil Aviation Authorities signed an agreement that would allow Tarom and KLM each to operate an unlimited number of flights between Bucharest and Amsterdam provided that both airline would give a timely notice to the other with respect to any schedule alteration
So based on these facts honestly, I don't see KLM willing to code share on the route. Was a mistake on the Rumanian Civil Authority signing such a gullible agreement . . .?
Maybe . . . but they'll have to live with it and learn from mistakes!
