Delta’s fanciest cabins are finding a home on three additional transatlantic routes.Specifically, the Atlanta-based carrier will fly its latest wide-body aircraft, which are equipped with the airline’s flagship Delta One Suites and Premium Select cabins, on the following three routes:Atlanta (ATL) to Rome (FCO) — Airbus A350-900, beginning April 11.Salt Lake City (SLC) to Amsterdam (AMS) – Airbus A330-900neo, beginning April 11.Salt Lake City (SLC) to Paris (CDG) – Airbus A330-900neo, beginning March 27.Delta upgauged the aircraft flying the first two routes during its weekend schedule update, as first seen in Cirium timetables and later confirmed by the carrier.(Photo by Zach Griff/The Points Guy)For now, the airline is planning to deploy its latest jets on the first two routes from mid-April to May 4, though it’s possible that the upgauge gets extended depending on booking patterns and other pandemic-related scheduling changes. Meanwhile, the Salt Lake City (SLC) to Paris (CDG) route will be operated by an A330neo from March 27 to Oct. 28.As always, be sure to monitor the seat map for your flight to stay on top of possible aircraft swaps and other cabin changes.Delta offers a few different types of business-class seats, ranging from its flagship suite product with a sliding door to an outdated forward-facing pod with limited storage and privacy on its Boeing 767-300 fleet.The airline’s two newest jets, the Airbus A330neo and A350, are the only ones in the fleet outfitted with Delta One Suites, which are a modified version of the Thompson Vantage XL seat. They’re arranged in a 1-2-1 configuration and provide ample space and privacy thanks to the sliding door found at each suite. (There currently aren’t any plans to retrofit Delta’s other wide-body jets with the suite product.)(Photo by Zach Griff/The Points Guy)These cabins have historically been deployed on the airline’s highest-profile international routes, such as from Detroit (DTW) to Tokyo (HND) and Atlanta (ATL) to Johannesburg (JNB).Now that U.S. airlines continue to pare back their Asia flying due to the pandemic, it makes sense for Delta to send its flagship jets on transatlantic missions, especially in the lead-up to what’s poised to be a busy summer travel season.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

To date, the airline hasn’t flown its Delta One Suites on any long-haul flights to or from the city.That’s changing in a big way though with the introduction of the flagship product in a few weeks. Locals based in the area and those who frequently connect through the city will undoubtedly enjoy the upgraded onboard experience.Along with Delta One Suites, the airline’s Airbus A330neo and A350 feature a Premium Select cabin, which is the airline’s take on the premium economy experience.Arranged in a 2-3-2 and 2-4-2 configuration respectively, these seats resemble domestic first-class recliners but offer some additional bells and whistles, such as a leg rest, footrest and larger entertainment screen.(Photo by Zach Griff/The Points Guy)Priced at a more modest upgrade compared to business, these seats offer additional space without breaking the bank for the flagship Delta One Suites product.Whichever product you choose, it’s great to see Delta spreading the love around its hubs with its nicest cabins.
