United Airlines has upgraded its flat-bed seat premium cabin. The enhanced transcontinental “p.s.” premium service, offered on United’s Boeing 757s, includes all new interiors, personal on-demand entertainment, Gogo Wi-Fi connectivity, in-seat power and USB ports.

The refreshed cabin features 28 BE Aerospace flat-bed seats, replacing 12 angled lie-flat and 26 reclining seats, which equip its traditional p.s. fleet. The new configuration also offers 48 extra-legroom economy plus seats and 66 seats in economy class. Newly designed Panasonic inflight entertainment touch-screens measure 15.4 in. in the premium cabin and 9 in. in economy.

The first flight to offer the new seats in its p.s. cabin was on a Los Angeles-New York JFK flight March 18. United launched p.s. service in 2004 and offers the enhanced class on all nonstop flights from New York JFK to Los Angeles (40 flights weekly each way) and San Francisco (46 flights weekly each way).

United began offering Gogo inflight connectivity in 2009, and in 2012 introduced the 180-degree flat beds in premium cabins. It plans to launch additional reconfigured aircraft in June and reconfigure the entire p.s. fleet by year end.
