Delta has announced new routes to Munich and Naples for summer 2024, as part of what it says will be its largest transatlantic schedules next year.

The US carrier will offer daily nonstop flights between New York JFK and Naples from 23 May, 2024, adding to Delta’s existing Italian routes to Milan, Rome and Venice.

The airline will also launch a thrice-weekly service between JFK and Munich beginning 9 April, 2024. Delta will compete with Lufthansa on the route.

Finally the carrier will resume flights between JFK and Shannon on 23 May next year – the first time the route has operated since 2019. Aer Lingus also flies between the two airports.

The resumption of the Shannon route follows the airline’s recent announcement of new flights between Minneapolis St-Paul and Dublin for summer 2024.

In total Delta will offer nearly 260 weekly flights from JFK to 18 countries across Europe, Africa and the Middle East next summer.

Meanwhile from Atlanta the airline will operate four-times-weekly flights to Zurich beginning 31 May, 2024, and will also add frequencies from Atlanta to Paris and Venice next summer, as well increasing flights from Cincinnati and Detroit to Paris, from JFK to Barcelona, from Detroit to Reykjavik, and from Boston to Athens.

Transpacific routes will also be boosted, with Delta’s Los Angeles-Auckland route (which launches on 28 October) being extended to year-round, and flights from LAX to Sydney increasing to twice-daily from December.

And a year-round service between Los Angeles and Shanghai-Pudong airport will resume on 31 March, 2024, operating four-times-weekly.

The airline recently completed its $2.3 billion Delta Sky Way project at LAX, and currently serves 13 international cities from the airport including London., Paris, Tokyo and Sydney.
