United has started flying a new breed of Boeing 787-9, and it's the most premium Dreamliner layout the airline has ever put in the sky. Branded United Elevate, these jets carry just 222 seats — 35 fewer than the existing 787-9s — which means a lot more space devoted to business and premium economy.
The headline product is the new Polaris business class, with 64 seats in a 1-2-1 layout across 16 rows. The front row is reserved for Polaris Studio, United's new "business class plus" tier with eight enhanced suites. Behind that sit 35 Premium Plus premium economy seats in a 2-3-2 configuration, and 123 economy seats in a 3-3-3 layout, including 39 extra-legroom Economy Plus spots. United expects 33 of these jets in the fleet by 2028, with deliveries arriving at roughly one per month — 16 are already flying.
So where do you actually find them? Currently the planes are based at two hubs: San Francisco (SFO) and Houston (IAH). From San Francisco, they're scheduled on London Heathrow flights (UA901/900 and UA930/939) and on the Singapore routes (UA1/2 and UA29/28), with Sydney service joining on 2 December 2026. From Houston, they serve São Paulo (UA62/63), Sydney (UA101/100) and Tokyo Narita (UA7/6), with daily London Heathrow flying from 5 January 2027.
How do you tell if your flight gets one? There's no flashy indicator at booking — your best clue is "Polaris Studio available" showing under the Polaris fare options, or a look at the seat map. And as always with anything tied to Boeing deliveries, schedules can shift, so check close to departure. Some flights between the two hubs also use these planes for repositioning, but without the full onboard soft product you'd get on an international route.
Why does this matter for travellers? Beyond the newer seats and cabins, the sheer number of premium seats makes these planes a smart pick for award redemptions and upgrades — more Polaris inventory means better odds with miles. If you've been sitting on a stash and want a front-row Polaris Studio suite, these routes are your earliest window to lock one in.
One caveat for perfectionists: the fleet hasn't yet been fitted with Starlink Wi-Fi, which United is rolling out across its fleet. If you'd rather experience the complete package, waiting a few months may pay off — though that also means sharing the Polaris Studio availability with everyone else who had the same idea.
Who is this for? Anyone flying long-haul from the US West Coast or Texas — particularly to London, Singapore, Sydney, Tokyo or São Paulo — who cares about the seat they'll spend 12+ hours in. Check the flight number against the lists above before you book, and you could end up in United's best cabin on day one instead of an older 787.
