Delta and officials from Massport Monday were finally able to celebrate a real estate plan that was meant to be executed 14 years ago.

The carrier now controls all 21 gates at Terminal A, its hub at Boston's Logan International Airport. Delta was slated to originally have full control of the terminal when it opened in 2005, but the carrier filed for bankruptcy and pivoted away from growing its Boston operation to focus on a merger with Northwest Airlines.

The airline’s eyes have since shifted back to Boston.

Delta named Boston a hub earlier this year, meaning the airline will begin to connect more passengers through Logan on top of its existing strategy of catering to travelers originating or ending travel in Boston. The hub model means more flights.

Delta, which bills itself as the city’s biggest global carrier (JetBlue is still Boston’s biggest airline by passenger and seat totals), will add a new flight to Rome and an additional flight to Paris on top of newly added international destinations like Lisbon and London-Gatwick, Manchester and Edinburgh in the UK, the company announced Monday.

That is good news for developers, as real estate analysts say more international flights help Boston grow its exposure to international investors. Delta and its partners, like Air France and Dutch airline KLM, now fly to 18 international destinations. Logan currently has flights to 57 international destinations overall.
