Delta Air Lines is expanding its transatlantic network for summer 2027 with two new European routes that will connect Boston and Detroit directly with Venice and Athens. The new services will give travelers in New England and Southeast Michigan additional nonstop options for reaching two of Europe’s most prominent leisure destinations, while also strengthening Delta’s position at two important U.S. gateways.
The new routes are Boston Logan International Airport (BOS) to Venice Marco Polo Airport (VCE) and Detroit Metropolitan Wayne County Airport (DTW) to Athens International Airport (ATH). Delta plans to operate the Boston–Venice service four times per week beginning May 7, 2027, while the Detroit–Athens route will operate three times weekly from June 8. Both services are seasonal and are scheduled to continue into late October.
The additions are part of a broader expansion of Delta’s European network for the 2027 summer season. Alongside the Boston and Detroit announcements, the airline is also preparing to launch Austin–Paris service, giving Austin its first nonstop connection to the French capital. Together, the three routes demonstrate how Delta is using seasonal long-haul flying to connect major U.S. markets with high-demand European destinations.
For Boston, the new Venice service will become Delta’s 13th long-haul destination from Logan International Airport. The airline already operates year-round service from Boston to Rome Fiumicino, while Milan Malpensa is served seasonally. During the peak summer period, Delta expects to offer 12 nonstop services to continental Europe, giving passengers a broad range of options for reaching the region without a connection.
Delta Boston to Venice Route Begins in May 2027
Delta’s Boston to Venice flights are scheduled to begin on May 7, 2027, with up to four weekly departures. The seasonal service is currently planned to operate through October 29, covering the core European summer travel period and extending well into the autumn shoulder season.
Venice is a particularly significant addition to Delta’s Italian network because of the city’s strong appeal to leisure travelers. The destination combines internationally recognized architecture, historic sites, canals, museums and access to the wider Veneto region, making it an attractive point-to-point market from Boston as well as a potential gateway for travelers continuing elsewhere in northern Italy.
The route will be operated with Delta’s Airbus A330-300, a widebody aircraft configured with four cabin products: Delta One, Delta Premium Select, Delta Comfort+ and Delta Main. This gives passengers on the seasonal transatlantic service a range of cabin options, from Delta’s lie-flat business-class product to its standard economy offering.
The new service also changes the competitive landscape for nonstop Boston–Italy travel. Delta will join ITA Airways as a carrier offering nonstop flights between Boston and Italy, although ITA’s nonstop Italian service from Boston is focused on Rome. Delta’s Venice operation therefore adds a distinct Italian destination rather than simply increasing capacity on an existing city pair.
Massport Executive Director of Aviation Sharon Williams highlighted the importance of Italy to the New England market, noting that the new route will provide another option for travelers seeking access to Italy while strengthening connections between the two regions. Delta’s continued investment also expands Boston’s role within its international network.
Detroit Gets Its First Nonstop Athens Service
The more distinctive development is Delta’s new Detroit–Athens route, which will begin on June 8, 2027. The service will operate three times weekly on a seasonal basis through October 28, creating the first nonstop connection between Detroit and Greece.
For travelers across Southeast Michigan, the route eliminates the need to connect elsewhere in the United States or Europe when flying from Detroit to the Greek capital. Athens is both a major destination in its own right and an important starting point for travelers continuing to Greece’s islands and other parts of southeastern Europe.
The service will also become Delta’s 12th long-haul destination from Detroit, while expanding the airport’s European network to seven destinations. Delta plans to deploy its Airbus A330-200 on the route, with Delta One, Delta Premium Select, Delta Comfort+ and Delta Main cabins.
Detroit will become Delta’s fourth U.S. gateway for Athens. The airline already serves the Greek capital seasonally from Atlanta, Boston and New York-JFK, giving it an established network of Athens services from several major U.S. markets.
The Detroit route can also benefit from Delta’s substantial domestic network at DTW. The airline serves up to 40 destinations from Detroit, allowing the Athens flight to draw passengers not only from Southeast Michigan but potentially from other parts of the Midwest through connecting itineraries.
Delta’s Summer 2027 European Expansion
| Route | Frequency | Aircraft | Start Date | End Date |
|---|---|---|---|---|
| Boston–Venice | 4x weekly | Airbus A330-300 | May 7, 2027 | October 29, 2027 |
| Detroit–Athens | 3x weekly | Airbus A330-200 | June 8, 2027 | October 28, 2027 |
The two new routes will launch alongside Delta’s planned Austin–Paris service. That route will connect Austin-Bergstrom International Airport with Paris Charles de Gaulle for the first time with a nonstop service and will also provide access to Air France’s extensive European network through Delta’s partnership with the French carrier.
Taken together, the changes show a clear emphasis on expanding nonstop access from U.S. cities to major European leisure markets during the peak travel season. Boston gains Venice, Detroit gains Athens, and Austin gains Paris, giving passengers in three major metropolitan areas new choices for summer travel in 2027.
For Delta, the strategy also allows the airline to add international capacity without necessarily committing every new route to year-round operation. Seasonal transatlantic routes can concentrate widebody aircraft where demand is strongest during the summer, while providing travelers with nonstop access during the period when European leisure travel is at its busiest.
