Which United aircraft have Premium Plus, and where should I book it?
Premium Plus is deployed on 787-9, 787-10, 777-300ER, and 767-300ER aircraft, but your experience depends heavily on the plane. Book it only on 787s (Dreamliners) for long-haul routes like SFO - NRT, LAX - LHR, and SFO - FRA, where you get a dedicated cabin and modern amenities. On 777-300ER and 767-300ER widebodies, Premium Plus occupies rows mixed with Economy Plus and offers minimal advantage, so avoid it on those aircraft.
What's the seat configuration and how do I pick a good seat?
On 787s, the layout is 2-3-2 (window, middle, aisle on each side); on 767s and 777s, it's 2-4-2. For couples, window/middle pairs (seats A/B or J/K) are ideal. On 2-4-2 aircraft, avoid the four-seat middle section (seats D - G) if flying solo, as you'll be sandwiched between strangers. Request seats in the first few rows of the cabin for faster boarding and galley access, but note that very front rows may experience more lavatory traffic and door noise.
What's the main drawback of Premium Plus on 767s and 777s?
On these aircraft, Premium Plus is deployed in a mixed cabin with Economy Plus, meaning narrower aisles, older lavatories, and no sense of separation from standard economy. The 38-inch pitch is identical to Economy Plus on some routes, and the recline advantage is marginal in a crowded cabin. You're paying significantly more for a seat that barely feels different from the cabin behind you.
How does United Premium Plus compare to Delta Premium Select?
Delta Premium Select typically offers wider 19.5-inch seats, better deployment consistency, and a more defined product with superior IFE on newer aircraft. Delta Premium Select is often cheaper than United Premium Plus for the same route and is consistently available on widebodies, whereas United's Premium Plus suffers from ad-hoc inventory and weak execution outside the 787 fleet. If both are available on your route, Delta Premium Select is usually the better value and more reliable choice.
