Delta One Suites now available on all of the carrier's 777 flights

This week, United Airlines reached a major milestone, with its new(ish) Polaris business-class seats now available on 100 wide-body planes. As it turns out, Delta's celebrating a similar accomplishment — all of the carrier's Boeing 777s now sport the airline's Delta One Suites, complete with a sliding door at every seat.

Now, business-class passengers traveling on Delta's 10 777-200LRs or eight 777-200ERs won't have to wonder about what they'll find onboard — just like on the Airbus A350 and A330-900neo, the carrier's entire 777 fleet offers a consistent onboard experience, with a total of 28 closed-door suites, 48 Premium Select recliners, 90 seats in Comfort+ and 122 in coach, with the latter two products arranged in a spacious 3-3-3 configuration.

Delta's 777s can be found flying around the world, and have recently operated a number of domestic and international flights.

From Atlanta (ATL):

• Johannesburg, South Africa (JNB)
• Los Angeles (LAX)
• New York (JFK)

From Los Angeles (LAX):

• Paris, France (CDG)
• Sydney, Australia (SYD)
• Tokyo, Japan (HND)

From Minneapolis (MSP):

• Tokyo, Japan (HND)

From New York (JFK):

• Mumbai, India (BOM)

While all of the airline's 777s flying passengers today sport the new products, Delta does have one 777-200LR still undergoing the retrofit process — N709DN. That particular aircraft is expected to return to service soon. For more on what to expect up front, see our ultimate guide to Delta One Suites.
