United’s top-notch Polaris business-class pods have made their way to another batch of aircraft.In a few short weeks, every Boeing 787-8 Dreamliner will be outfitted with United’s latest cabins, marking the end of the guessing game as to what onboard product your flight will feature.On April 29, the final 787-8 flying with the legacy interiors, registered N45905, landed in Xiamen, China to receive the Polaris and Premium Plus retrofit. (The second-to-last 787-8 with old seats has been in Xiamen since April 17 undergoing the same interior upgrade.)Want more airline-specific news?

I caught a ride on the first reconfigured -8 back in January 2020, and you can read my first impressions of the new cabin here.Two-row mini-cabin on the Boeing 787-8 (Photo by Zach Griff/The Points Guy)While the business-class cabin is downsized compared to the legacy interiors — making awards and upgrades harder to come by — the plane sports two of my favorite Polaris pods in the entire fleet, seats 6A and 6L. That’s because they’re located in an intimate two-row mini-cabin behind the second exit door, and feature oversized footwells and unrivaled privacy.With the reconfiguration, United introduced a Premium Plus cabin on the 787-8. It’s an intermediate offering between coach and biz that’s quite similar to domestic first class. Not much has changed in coach except for a more robust IFE system.If you’re hoping to try United’s 787-8 domestically in June, you’ll find it flying to a variety of airports in Hawaii, including on routes from Chicago (ORD) to Honolulu (HNL), Maui (OGG) and Kona (KOA), as well as from Washington/Dulles (IAD) to HNL, according to Cirium schedules.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

All “dash ten” jets were delivered with the new cabin pre-installed at the factory, leaving just the old -8 and -9 needing the retrofits.Now that the “baby Dreamliner” is complete, that leaves just the mid-sized 787-9 as the only Dreamliner type with a mix of new and old seats. Fortunately, United’s making significant headway in the -9 reconfigurations. 15 of the carrier’s 38 787-9s already have the new seats.First look: United’s retrofitted Boeing 787-8 DreamlinerIn a recent webinar with Brian Kelly, vice president of international network and alliances Patrick Quayle said that despite the pandemic, United is “working on a schedule” for the 23 787-9s that don’t yet feature the fancy pods. The carrier should have those completed by summer 2022.As for its other long-haul aircraft, all internationally-equipped Boeing 777-200ERs have the new cabins, though a good chunk of them are parked indefinitely due to the FAA’s airworthiness directive regarding the recent uncontained engine failure on a Pratt & Whitney-powered United 777-200.All 22 of United’s larger 777-300ER have the new seats as well.33 of United’s 38 Boeing 767-300s also have the new cabins, with some configured in a premium-heavy “high-J” layout sporting a whopping 16-row Polaris cabin with 46 pods.None of United’s 16 Boeing 767-400 sport the new cabins. Most are still parked in long-term storage due to the pandemic, though at least one is getting reactivated to compensate for the grounding of the Pratt & Whitney 777s.
