United Airlines (UA) , the carrier that increased the checked baggage fees by $10 due to the Iran War, on the will operate its latest-generation ‘Polaris 2.0’ Business Class cabin on both of its daily flights between Singapore Changi Airport (SIN) and San Francisco International Airport (SFO) from August 2, 2026 — meaning all 14 weekly frequencies between the two cities will feature the new product from that date, Mainly Miles reported.
The same source revealed that schedule data loaded into airline reservation systems confirms that the second daily rotation, operating as UA28/UA29, will join the existing UA1/UA2 service in receiving the new cabin, with the westbound UA29 departure from San Francisco picking up the product one day earlier, from August 1. This rollout delivers on a trajectory signalled when Polaris 2.0 first debuted on the SIN–SFO route barely three months ago.
With 64 Polaris Business Class seats aboard each of these Boeing 787-9 Dreamliners — including eight premium Studio Suites — United will offer 1,792 Business Class seats per week on the Singapore–San Francisco corridor from August, a 17% premium capacity lead over Singapore Airlines (SQ), which provides 1,526 Business Class seats weekly across its two competing daily A350 services.
United’s Full Singapore Schedule from August 2, 2026
From August 2, 2026, both of United’s daily Singapore–San Francisco departures will operate aboard Boeing 787-9 aircraft fitted with the airline’s new ‘Elevated’ interior. The morning UA2 departs Singapore Changi at 08:45 and arrives in San Francisco at 09:30 the same day, with a block time of 15 hours and 45 minutes.
The evening UA28 departs at 20:35, arriving at 21:20 local, also a 15-hour and 45-minute journey. In the opposite direction, UA29 departs San Francisco at 11:10, arriving in Singapore at 18:35 the following day (16 hours and 25 minutes), while UA1 departs at 22:50, touching down two days later at 06:15.
As Mainly Miles reported, the UA28/UA29 frequency had retained the older-generation Polaris seats when the new cabin made its route debut in late April on UA2/UA1. The pace of Boeing 787-9 deliveries under United’s ‘Elevated’ fleet programme has made this a short-lived split. Aviation A2Z confirmed that United currently has four Elevate-configured 787-9s in active service — registered N21102, N51104, N61101, and N61103 — all based at San Francisco, with a fifth delivery imminent and a further 66 aircraft in the pipeline at near-term delivery rates of approximately one per month.
The same new product already features on United’s daily UA900/901 San Francisco–London Heathrow Airport (LHR) service, with the second London frequency, UA930/939, set to receive the cabin from mid-May 2026. By September 2026, every daily United flight from San Francisco to London, Singapore, and Zurich Airport (ZRH) will feature the Elevated cabin product.
Inside ‘Polaris 2.0’: What the New Cabin Delivers
United’s new Business Class is a substantial departure from the original Polaris product that launched in 2016, and the aircraft housing it represents the most premium long-haul configuration ever fielded by a US carrier.
One Mile at a Time reported that the ‘Elevated’ Boeing 787-9 carries just 222 total seats — the least-dense configuration of any American airline widebody — including 64 Polaris Business Class seats in a 1-2-1 layout with direct aisle access for all passengers, 35 Premium Plus premium economy seats, and 123 economy seats. Less than half the aircraft is configured in standard economy, a deliberate skew toward high-yield passengers.
The new Polaris seat is a customized version of the Adient Aerospace Ascent model in a 1-2-1 configuration and includes sliding privacy doors — though these remain locked open pending FAA regulatory approval at the time of writing.
Each seat features a 19-inch 4K seatback screen, wireless charging, USB-C and traditional power outlets, Bluetooth audio pairing, and custom mood lighting. Free Starlink Wi-Fi is available across all cabins on these aircraft, a meaningful differentiator on a flight exceeding 16 hours.
The eight Studio Suites, occupying the front row of each Business Class cabin section, constitute a distinct tier within the cabin. Simple Flying reported that the Studio features 27-inch 4K OLED screens — the largest fitted in any US carrier’s business class — additional suite area, an ottoman seat permitting companion dining, and a supplementary service featuring Ossetra caviar and Laurent-Perrier Cuvée Rosé Champagne. Access to the Studio Suites carries a surcharge of US$499–599 over a standard Polaris fare.
The Points Guy, which reviewed the product on the inaugural UA1 departure from San Francisco, noted that a frequent flyer — a United million-miler — paid half a million miles for a standard Polaris seat on the inaugural flight, then paid an additional US$600 to upgrade to a Studio Suite, describing the investment as befitting United’s ambition to close the gap with its rivals’ premium offerings.
All in All
The pace of United’s ‘Elevated’ 787-9 programme is central to understanding how quickly Polaris 2.0 will colonise the carrier’s long-haul network. One Mile at a Time reported that United expects to take delivery of 20 new Dreamliners with the ‘Elevated’ cabin in 2026 alone — a figure the airline itself described as the highest annual widebody intake of any US carrier since 1988.
With a further 66 aircraft in the order pipeline beyond the current four in service, the rollout trajectory points to rapid and systemic network coverage across United’s most competitive international routes.
