In October, CNAB said that its gross profit rose 34% year-on-year to 320 million lei ($81.6 million/ 68.7 million euro) in the first nine months of 2017 due to significantly higher revenues and a more efficient management of financial resources.
In September, CNAB said it intends to start construction of a new terminal worth 818.5 million euro ($971 million) which will double the combined capacity of the company's two airports. The works are expected to begin in 2022 and will take three years to complete. The new terminal at the Henri Coanda airport will have 25 gates and 56 parking spaces.
