Delta Air Lines will fly from Worcester Regional Airport to Detroit, officials announced Tuesday morning, connecting Central Massachusetts travelers with more than 100 locations around the world.

Flights are expected to begin around August 2019.

Lt. Gov. Karyn Polito and Massport officials said Detroit allows people access to 134 destinations, including locations in Asia and Europe.

"Delta to Detroit sounds pretty good to me," Polito said. "We're really thrilled to have this connection between Worcester and Detroit through Delta Air Lines."

Polito called the flights one more asset for Central Massachusetts and another item in the toolbox to bolster the economy and build on the momentum in Worcester and the region.

What time the flight will depart from Worcester Regional Airport and how much tickets will cost have not yet been determined. The contract has been signed and the commitment has been made, officials said, but the project hinges on ongoing construction with additional Delta gates coming to Logan International Airport in Boston.

The Delta Worcester to Detroit Metropolitan Airport flight will be operated by Delta Connection carrier SkyWest Airlines, Massport said.

The flights will be an asset for the business community, as well as students looking at colleges, officials said.

"Detroit is a city that is on the move, like Worcester," Polito said. "It's populated with connections to many colleges and universities...I think there's a real connection between the Worcester story, what's happening here around manufacturing, bio, life sciences and our colleges and universities, and Detroit. And of course, the sports teams as well. And the culture, I think there's a lot of synergies there."

Worcester County Sheriff Lewis Evangelidis, who chairs the Massport board, urged residents to fly out of Worcester.

Evangelidis said the most exciting part of flying to Detroit will be the options to connect to other cities around the world.

"People may say, well Detroit, I don't know if I want to go to Detroit," Evanglidis said. "It's the whole idea. Detroit offers a lot, but there are so many connecting flights out of Detroit. So it's just going to be an incredible asset for us in Worcester County, this region, to have another major player in this market that will open the world to us."

There are 450 daily departures from Detroit Metropolitan Airport. The airport serves a total of 16 total airlines, which offer 1,100 daily flights to and from four continents. The airport served more than 33 million passengers last year.

This is the second major airline to announce new flights out of Worcester Regional Airport this year and the third major service announcement in 18 months.

In October, two daily American Airline flights are slated to begin between Worcester Regional Airport and Philadelphia International Airport.

Delta and American join JetBlue, which has been offering daily flights out of Worcester for five years.

Since 2013, JetBlue has flown daily to Orlando and Fort Lauderdale.

Since the airline came to Worcester, more than 500,000 passengers have flown on JetBlue through Worcester Regional Airport.

In May, JetBlue expanded its service with the addition of daily flights to John F. Kennedy International Airport in New York City.

Rectrix Aviation also offers a 20-minute flight to Cape Cod out of Worcester.

At its peak in 1989, Worcester Regional Airport served more than 340,000 people.

Massport owns and operates Worcester Regional Airport, in addition to Boston Logan International Airport, public terminals in the Port of Boston and Hanscom Field.
