United adding seats to 777-200s with Polaris retrofit

United Airlines will add at least 23 seats to its long-haul Boeing 777-200s when it reconfigures the aircraft with its new Polaris business class seats. The carrier will configure the aircraft with 50 lie-flat Polaris business seats and 242 economy seats, shows a seating diagram sent to flight attendants and provided to FlightGlobal by a source. United configures its long-haul 777-200s with either 267 seats or 269 seats, depending on whether they are former Continental Airlines or United aircraft. Its domestic 777s have 364 seats and will not receive Polaris. The airline joins competitors American Airlines and Delta Air Lines adding seats to its 777-200s. American is reconfiguring its fleet of the type with up to 289 seats compared to 247 seats previously, and Delta plans to retrofit its fleet with 296 seats versus 291 seats today.<br/>
