Delta Begins Flights From Seattle to Barcelona and Rome

Delta Air Lines announced its summer 2026 plans right after summer 2025 ended. Last year, the Atlanta-based carrier announced plans for nonstop service from Seattle (SEA) to both Barcelona (BCN) and Rome (FCO).

The flight to Rome starts today, May 6, while the Barcelona flight kicks off tomorrow, May 7, 2026.

“We welcome the opportunity to grow our partnership with Delta as they expand Seattle’s connections to international communities and businesses,” said Port of Seattle Commissioner Fred Felleman.

Here’s what you need to know.

Delta Begins Seattle Flights to Barcelona and Rome

Delta Air Lines is commencing its nonstop flights from Seattle-Tacoma International Airport (SEA) to both Barcelona (BCN) and Rome (FCO) this week.

The flight to Rome (flight DL42) starts today, May 6, at 1:55 p.m. local time. Flights will operate 4x weekly on Mondays, Wednesdays, Fridays, and Sundays.

Meanwhile, the flight to Barcelona (DL248) starts tomorrow, May 7, at 3:25 p.m. local time. Flights will operate 3x weekly on Tuesdays, Thursdays, and Saturdays.

Delta will fly its Airbus A330-900neo jet on both routes. This 281-seat jet features Delta One business class with full-height privacy doors and Premium Select.

The airline says it has launched 28 new destinations from its Seattle hub over the past decade.

These will be much-needed routes for Seattle, which lacked nonstop flights to both Barcelona and Seattle until recently. Interestingly, Alaska Airlines started Seattle-Rome flights at the end of April, and Delta will become the second carrier on the route. Delta will be the only airline flying Seattle-Barcelona nonstop.

How To Book

If you’re looking to book these flights, fares are available using cash and points.

If you’re paying for a flight, Google Flights and Delta.com have calendar features that can help you find the cheapest dates.

Meanwhile, if you’re planning to use points and miles for your flight to Europe, you have options.

If you’re flying in economy, Delta SkyMiles is charging 45,100 miles per person one-way in economy, while we’re seeing awards through Virgin Atlantic Flying Club for 30,000 points.

Flying in Delta One business class has fewer options right now. We’re not seeing any partner awards, and Delta is charging 300,000+ miles per person one-way on these flights on most dates. There are some dates available for 260,000 miles, but that’s still a bad price.

Final Thoughts

Delta’s addition of flights to Barcelona and Rome from Seattle is fantastic news, especially considering that it’s the only carrier flying this nonstop route to Barcelona. Just recently, Seattle didn’t offer nonstop flights to Rome, and now locals have 2 options in 2 different alliances.
