Slowly.More than three years have now passed since United CEO Oscar Munoz unveiled the carrier’s much-improved business-class product. This week, Patrick Quayle, UA’s Vice President of International Network, confirmed that the carrier is on track to hit a major milestone by the end of 2019.Polaris business class on United’s “high-J” 767-300ER.

The first 787-9 with the new seats — the longer-range version used for some of United’s most premium routes, like San Francisco (SFO)-Singapore (SIN) and Newark (EWR)-Cape Town (CPT) — will follow a few months later.United’s “dorm-style” business class will soon be no more — except on a handful of regional 777s. Photo by Zach Griff / The Points Guy.Quayle pointed out that roughly one-third of United’s existing fleet has now gone through the retrofit process — new deliveries make up the remaining aircraft. Eventually, most of United’s roughly 200 wide-body planes will offer the new seats, though some 777-200s, used for domestic and regional flights, are expected to continue operating with the carrier’s dated 2-4-2 product — not-so-affectionately referred to as “dorm-style” business class by frequent flyers.
