Delta Air Lines will inaugurate daily, nonstop service between John F. Kennedy International Airport (JFK) and Francisco Sá Carneiro Airport (OPO) in Porto on May 21, 2026. The route will operate on a Boeing 767-300ER with Delta One, Premium Select, Comfort, and Main cabins, expanding the carrier's Portugal footprint beyond Lisbon. The Porto launch headlines a seven-route transatlantic expansion for summer 2026 that also introduces Sardinia and Malta from New York and adds new Boston and Seattle links into Spain, France, and Italy.

Key points

Why it matters: Daily JFK-Porto flights give travelers a second nonstop U.S.-Portugal gateway on Delta.
Travel impact: Added seats to Iberia and the central Med should ease summer constraints and improve connectivity.
What's next: Sardinia starts May 20, 2026; Malta on June 7, 2026; Boston and Seattle growth rolls out in May.
JFK-Porto uses a 767-300ER; Seattle routes use A330-900neo.
Boston adds Madrid and Nice; Barcelona and Milan frequencies move up in season.

Snapshot

Starting May 21, 2026, Delta will fly daily between JFK and Porto, tapping strong U.S. demand for northern Portugal, Douro Valley wine country, and the broader Northwest Iberia region. The 767-300ER equips lie-flat Delta One, Premium Select, fast free Wi-Fi for SkyMiles members, and an updated soft-product. The Porto move complements year-round JFK-Lisbon and seasonal Boston-Lisbon, while Boston gains new links to Adolfo Suárez Madrid-Barajas Airport (MAD) and Nice Côte d'Azur Airport (NCE). On the West Coast, Seattle-Tacoma International Airport (SEA) gets new seasonal service to Josep Tarradellas Barcelona-El Prat Airport (BCN) and Rome-Fiumicino (FCO) aboard A330-900neos. Delta also adds first-ever U.S. nonstops to Olbia Costa Smeralda Airport (OLB) in Sardinia and Malta International Airport (MLA).

Background

Porto has evolved into a high-yield leisure and visiting-friends-and-relatives market, buoyed by hotel growth and improved regional connectivity. For New York area travelers, the JFK-Porto addition arrives as the region manages long-term slot and delay pressure; more nonstop options help distribute demand across gateways. (Related: Newark flight cap extended to 2026.) Delta positions JFK as the launchpad for multiple Mediterranean debuts, letting travelers pair Northern Portugal with new island escapes. The airline's Boston and Seattle expansions deepen coverage across Spain, France, and Italy, with schedules staged to meet peak summer leisure flows and shoulder-season starts.

Latest developments

JFK to Porto flights start May 21, 2026

Delta's first-ever JFK-Porto route begins May 21, 2026, operating daily with a Boeing 767-300ER. The onboard product includes Delta One lie-flats, Premium Select, Comfort, and Main, plus Missoni amenity kits and Taittinger service in Delta One. Delta highlights Porto's Douro-river access and the route's fit with its broader Portugal strategy alongside JFK-Lisbon and BOS-Lisbon.

Two new island routes from JFK: Sardinia and Malta

Following Delta's Route Race vote, JFK-Olbia launches May 20, 2026, four times weekly on 767-300ERs, and JFK-Malta launches June 7, 2026, three times weekly. Airport leaders in Olbia and Malta framed the flights as historic firsts that strengthen tourism and business ties and add a direct U.S. link.

Boston adds Madrid and Nice; Barcelona and Milan ramp up

From Boston Logan International Airport (BOS), Delta starts daily Boston-Madrid on May 16, 2026, and three-times-weekly Boston-Nice on May 17, 2026. The carrier also advances seasonal Barcelona and Milan service to earlier start dates, boosting options for New England travelers heading to southern Europe.

Seattle gains Barcelona and Rome with A330-900neos

At Seattle-Tacoma International Airport (SEA), new seasonal flights launch May 6, 2026, to Rome (four weekly) and May 7, 2026, to Barcelona (three weekly). Both use the A330-900neo with Delta One Suites and Premium Select, supporting SEA's long-haul growth alongside new premium lounge investments.

Analysis

Delta's 2026 transatlantic push targets durable, leisure-heavy O&D while reinforcing coastal hubs where the airline controls feed and premium share. Porto extends Delta's Portugal presence beyond Lisbon to a market with rising U.S. awareness, wine-region appeal, and strong visiting-friends-and-relatives demand. The daily cadence and 767-300ER gauge signal confidence in shoulder-season viability, while product consistency helps preserve yield. Sardinia and Malta, both unserved nonstop from the U.S., give JFK distinctive Mediterranean inventory that competitors cannot quickly match, and the Route Race device builds SkyMiles engagement. Boston's mix of Madrid, Nice, and earlier Barcelona and Milan starts aligns with New England's summer-peaking leisure profile. Seattle's A330-900neo deployment to Rome and Barcelona widens West Coast coverage with efficient, right-sized frequency. Taken together, the seven-route bundle spreads risk across geographies yet concentrates brand heat where Delta's lounges, schedules, and alliance partners can amplify conversion.

Final thoughts

For travelers, daily JFK-Porto unlocks northern Portugal with a simple, year-round-friendly schedule and a familiar widebody product. Advisors can package Douro Valley wine trips with new JFK island options or pair Iberia with Seattle's fresh links to Barcelona and Rome for open-jaw itineraries. As Delta layers Sardinia, Malta, Madrid, and Nice into its map, summer choices multiply and pricing pressure could ease at the margins. If Porto, the Douro, or the Med are on your list, watch for fare sales tied to these route launches, then build plans around the new JFK to Porto flights.
