I don't have great confidence in any Bucharest taxi company. All taxis display their rates on the car. They vary form 1 - 3.3 Lei per kilometre (~50ct to 1,5US$) as the airport is not very far from Bucharest it should cost something between 20-60 Lei. But you cannot relay on the taxi driver to take the most direct routing. I also was told not to put luggage in the trunk. I was told that some drivers would refuse to open the trunk until you paid them far more than they deserved.
Make sure that a meter is in the cab and functional. The only bad experience I had was with the 'official taxi company: Fly' at the airport. The driver took a route twice as long as needed.
But besides the taxi drivers I really enjoyed the city!!
