Delta Airlines is adding two new nonstop European routes for summer 2027—Boston to Venice and Detroit to Athens while also extending several existing transatlantic services into earlier spring or later fall and winter periods. The new flights complement Delta’s previously announced Austin–Paris service and form part of a broader expansion of its European schedule.
The changes give travelers more opportunities to reach Europe without waiting for the traditional peak summer window. For passengers in Boston, Detroit, Austin and several other U.S. markets, the 2027 schedule introduces new nonstop options while extending the operating periods of established seasonal routes.
Here is what travelers need to know about Delta’s new European routes, operating dates, aircraft, frequencies, and the expanded 2027 transatlantic season.

The two newly announced routes connect Boston Logan International Airport (BOS) with Venice Marco Polo Airport (VCE) and Detroit Metropolitan Wayne County Airport (DTW) with Athens International Airport (ATH).
| New route | Launch date | Planned end date | Frequency | Aircraft |
| Boston–Venice | May 7, 2027 | Oct. 29, 2027 | 4 times weekly | Airbus A330-300 |
| Detroit–Athens | June 8, 2027 | Oct. 28, 2027 | 3 times weekly | Airbus A330-200 |
| Austin–Paris | March 27, 2027 | Seasonal summer service | Daily | Airbus A330-900neo |
The Boston–Venice and Detroit–Athens services are seasonal. Dates and schedules remain subject to operational changes, so travelers should verify the itinerary when booking. Delta announced the routes on September 25, 2026.
Delta will launch four-times-weekly nonstop service between Boston and Venice on May 7, 2027, with the seasonal operation scheduled to continue through October 29. The route will connect Boston Logan with Venice Marco Polo Airport.
The service is particularly significant for Delta’s Boston operation because Venice will become the airline’s 13th unique long-haul destination from Boston during the peak summer season and its 12th destination in continental Europe, according to Delta.
Boston will also become Delta’s third U.S. gateway to Venice. The airline says the service will provide connections to nearly 20 destinations across the United States, giving passengers beyond Boston another way to reach Venice with a connection.
Delta plans to operate the route with an Airbus A330-300, a widebody aircraft used across its long-haul network.
The aircraft will offer four cabin products:
That gives passengers several cabin choices depending on the fare and travel experience they want.
The Venice service also adds capacity to an already substantial Delta network between the United States and Italy. Delta says that in 2027 it expects to offer as many as 17 peak-day departures from the U.S. to Italy and more than 30,000 nonstop seats to Italy each week.
The Venice announcement is not the only Italy-related change at Boston.
Delta says its Boston–Milan service will increase to daily in 2027. This means travelers heading to northern Italy will have a more frequent option alongside the new Venice route.
For passengers planning an Italy trip, the two markets serve different purposes. Venice provides direct access to northeastern Italy and the Veneto region, while Milan can work as an entry point for northern Italian cities and onward European travel.
Delta will introduce three-times-weekly nonstop service between Detroit and Athens beginning June 8, 2027. The seasonal flights are scheduled to operate through October 28.
This will be a new nonstop option for travelers in Southeast Michigan. Delta says Athens will become its 12th unique long-haul destination from Detroit during the peak summer season and its seventh destination in continental Europe.
It will also make Detroit Delta’s fourth U.S. gateway to Athens.
The Detroit–Athens service is scheduled to use an Airbus A330-200.
Like the Boston–Venice service, it will feature:
The widebody configuration suits the long transatlantic journey while giving passengers several cabin options.
The new Athens service is not aimed only at passengers starting in Detroit.
Delta says travelers can connect through Detroit to more than 40 U.S. destinations. That makes the route relevant to passengers elsewhere in Delta’s domestic network who want to reach Greece without starting their journey in Southeast Michigan.
For example, a traveler originating in another U.S. city could potentially connect through Detroit before continuing nonstop to Athens, subject to the published schedule and available connections.

The two new routes are part of a wider European expansion rather than standalone additions.
Delta had already announced daily nonstop service between Austin-Bergstrom International Airport and Paris-Charles de Gaulle beginning March 27, 2027. The route will be Austin’s first-ever nonstop service to Paris.
The Austin–Paris flight is planned to operate with an Airbus A330-900neo featuring:
Beyond Paris itself, the route is important for connecting passengers. Delta says its partnership with Air France-KLM will provide one-stop access to nearly 70 destinations across Europe, India and Africa from Austin via the wider network.
The most notable part of Delta’s announcement isn’t just the two new routes. The airline is also changing when several existing European routes operate.
Traditionally, many leisure-focused transatlantic flights are concentrated around the summer travel season. Delta’s 2027 schedule will push several services earlier into spring, while some routes will continue deeper into fall or winter.
The changes include:
| Route or market | 2027 schedule change |
| Minneapolis–St. Paul–Rome | Seasonal service begins in early March |
| Detroit–Rome | Seasonal service begins in early March and will operate daily when it resumes |
| Seattle–Rome | Service begins in April |
| New York-JFK–Catania | Returns earlier |
| New York-JFK–Porto | Returns earlier |
| New York-JFK–Prague | Returns earlier |
| New York-JFK–Copenhagen | Returns earlier and will operate daily when it resumes |
| Boston–Barcelona | Returns earlier |
| Seattle–Barcelona | Returns earlier |
| Atlanta–Edinburgh | Returns earlier |
| Cincinnati–Paris | Continues 3 times weekly from January through March |
Delta announced these adjustments as part of its effort to provide more transatlantic availability outside the core summer period.
A longer European operating season can be useful for passengers who do not want to travel during the busiest part of summer.
Earlier service gives travelers additional opportunities to visit Europe in March, April and the shoulder-season weeks before the traditional summer peak.
For example, Delta’s Detroit and Minneapolis–St. Paul services to Rome will begin in early March, while Seattle–Rome will resume in April.
Several routes will continue or return during the fall period, including the newly announced Boston–Venice and Detroit–Athens flights.
This matters for travelers looking for European trips later in the year, although actual weather, tourism levels and attraction schedules vary by destination.
The extension also reaches beyond the typical summer schedule in some markets. Cincinnati–Paris, for example, is planned to continue three times weekly from January through March.
That gives Cincinnati-area travelers an additional seasonal transatlantic option during a period when many leisure routes traditionally operate less frequently.
The 2027 additions build on a significant expansion of Delta’s transatlantic network during 2026.
For summer 2026, Delta introduced seven new transatlantic routes, including services connecting Seattle with Rome and Barcelona, Boston with Madrid and Nice, and New York-JFK with Olbia, Porto and Malta. Delta said those additions brought its summer schedule to more than 650 weekly flights to nearly 30 destinations across Europe, which the airline described as its largest transatlantic schedule at the time.
The 2027 announcements therefore continue a broader network strategy: add nonstop routes from major U.S. gateways while making existing seasonal routes available for more of the year.
The network also benefits from Delta’s transatlantic joint venture relationships with Air France, KLM and Virgin Atlantic, along with other airline partnerships. These relationships can expand the number of destinations available beyond Delta’s own nonstop network.

The Boston–Venice announcement strengthens an airport that already plays an important role in Delta’s transatlantic network.
Delta identifies Boston as its closest U.S. hub to Europe. The airline’s 2027 plan combines the new Venice route with increased Boston–Milan service and its existing European network.
For travelers, this means Boston can function not only as an origin point but also as a connecting gateway for passengers traveling between other U.S. cities and Europe.
Detroit is also a major Delta connecting point. The new Athens service adds Greece to the airport’s European network and gives passengers from more than 40 U.S. destinations the potential to connect onward to Athens through Detroit.
The route is particularly relevant for travelers visiting mainland Greece, although Athens can also serve as a starting point for onward trips to Greek islands and other destinations through separate air or ferry connections.
Because the new services are seasonal, passengers should look beyond the headline route announcement before finalizing a trip.
A route operating during summer does not necessarily operate every day throughout the broader season. Boston–Venice is planned four times weekly, while Detroit–Athens is planned three times weekly.
A traveler choosing a specific vacation date should therefore check the actual flight calendar rather than assuming daily availability.
A nonstop flight can save connection time, but schedules and fares may vary by date. Passengers should compare the complete itinerary, including departure times, arrival times, connection requirements and cabin.
Delta has specified different A330 variants for the new routes:
All three are planned with Delta’s major long-haul cabin products, although exact seat maps and aircraft assignments can change.
Airline schedules can change because of operational requirements, aircraft availability, government approvals, or other factors. The published itinerary should be treated as the current reference when making a booking.
