United Airlines has completed cabin upgrades to the 15 Boeing 757-200s in its Premium Service (PS) fleet.
The retrofitted aircraft are now configured with 28 flat-bed BusinessFirst seats, 42 economy plus seats and 72 economy seats, as well as person audio video on demand and power outlets at every seat, according to the Chicago-based Star Alliance carrier.
The PS 757s fly between New York JFK and both Los Angeles International and San Francisco International airports.
The upgrades come as both American Airlines and JetBlue Airways plan to roll out new premium products on the routes in 2014, upping competition for premium customers on the already competitive route.
Delta Air Lines flies Boeing 757-200s and Boeing 767-300ERs in international configurations, and Virgin America its standard product that is designed for transcontinental service on the routes.
United introduced its first updated PS 757 this past March.
The airline offers satellite-based wi-fi on the aircraft.
