Delta Air Lines will resume its nonstop daily summer service between Lisbon and Boston starting on May 9, 2023. The service  will be operated until October 27, an extension that has not happened since its launch in 2019, and will complement the popular annual service between Lisbon and New York-JFK – also daily in this period.

In total, Delta will offer 14 weekly flights between Portugal and the United States this summer, with up to 430 seats daily, including in Delta Premium Select and Delta One upper cabins. Both services offer customers increased choice to destinations across the U.S., thanks to convenient onward connections via Delta’s New York-JFK and Boston hubs.

“Delta’s nonstop flight between Lisbon and Boston, which we are excited to serve since 2019, allows our customers from Portugal to connect to an expanded number of destinations across the U.S. and beyond via one of our most dynamic and fast-growing hubs across the Atlantic,” said Vice-President Nicolas Ferri of the EMEAI region of Delta Air Lines. “At the same time, this resume of summer service allows our North-American leisure and business clients – one of top 5 source markets in terms of revenues – to reach an increasingly popular destination in our network and explore the country’s rich history and heritage, but also help furthering the local travel industry.”

President of Turismo de Portugal Luís Araújo called the return of the route “a relevant proof of the tourist recovery that is taking place in Portugal. It is especially important when the United States is one of our main outbound markets, providing tourists with an option with the quality of Delta Air Lines.”

“We are delighted to welcome back the Delta Air Lines nonstop service between Lisbon and Boston this summer,” says Executive Director Keiko Matsudo Orrall of the Massachusetts Office of Travel & Tourism. “Massachusetts has a proud Portuguese American community in New Bedford and Provincetown, and vibrant traditions of culture, heritage, education, cuisine, and scenic beauty that we can’t wait to share. As the gateway to all of Massachusetts and the six New England states, Boston is a perfect place to start on your American adventure.”

Chief Commercial Officer Francisco Pita of ANA – VINCI Airports, said, “The reinforcement of Delta Air Lines’ operation from Boston shows the growing enthusiasm of the North American market for Portugal, particularly for Lisbon.  This continues to be one of the markets that has been growing the most after the pandemic, contributing to the rapid resumption of air traffic at Portuguese airports. The direct connections, such as Boston – Lisbon, consolidate and stimulate the market, so I thank our teams, ANA|VINCI Airports, Delta Air Airlines and other partners for the excellent work done for the sustainability of this route and the connectivity of the country.”

Delta’s year-round flights to New York-JFK and summer service to Boston are operated with Boeing 767-300 aircraft and in conjunction with Delta’s transatlantic joint venture partners Air France, KLM and Virgin Atlantic.
