Depending upon the time of year, Air Pacific Fiji offers between three and five weekly non stop 747s between Los Angeles and Fiji’s gateway city Nadi. Flights take approximately ten and a half hours. Departures from Los Angeles are either 10:30 or 11:30pm depending upon daylight savings time seasons. Because you will cross the International Dateline en route, flights arrive in Nadi at 5:10am two days later.
On your return flight you “regain” the lost day; flights depart Nadi late in the evening, arriving in Los Angeles early in the afternoon of the same calendar day that you departed Nadi.
Connecting flights from other US and Canadian cities can be arranged by Impulse; however, the way airline reservations systems are now set up, it is most likely that you can arrange a much better fare to Los Angeles by contacting appropriate airlines directly from your home city of town.
