Best Airline To The South Pacific
No line to the South Pacific met our minimum criteria. Your best bet is Virgin Australia's 777, at a 32-inch pitch, from Los Angeles. Virgin Australia partners with Alaska, Delta, Frontier, Hawaiian, and US Airways for domestic connections.
Extras: Audio/video at each seat.
Also Good to the South Pacific: Consider Air New Zealand's 777-200, at a 31–33-inch pitch with nine seats across, but avoid that line's 777-300, with ultratight 10-across seats.
