United's longest route, SFO-SIN, operates a 222-seat 787-9 with 64 Polaris seats, making award space scarce in premium cabins. The new EWR-ICN route launching September 4 uses a less premium 257-seat 787-9, potentially offering more economy award availability. Meanwhile, the seasonal SFO-ADL route runs only December 17 to February 8 with historically low 52.7% loads, a narrow window for off-peak award seekers.
