NATIONAL air carrier Air Pacific says the delays experienced because of an engine change on one of its aircraft resulted in a schedule change.
A statement issued by the airline said the delayed scheduled engine change to its B747-400 aircraft in Los Angeles had resulted in the departure and arrival time changes for the LA and Auckland serviced routes.
The airline said the Los Angeles/Nadi flight initially scheduled to depart LA 1:05pm Tuesday, departed at 2:35pm instead and arrived in Nadi at 9:20pm yesterday.
It said the next Los Angeles/Nadi service that was scheduled to depart LA at 10pm on Tuesday, was rescheduled for 8am yesterday, and would now arrive into Nadi at 2:30pm today.
The airline said because the delay of the inbound aircraft from Los Angeles, today's Nadi/Auckland/Nadi service would also be affected.
"Air Pacific has chartered an aircraft from Air New Zealand to service this sector, as a result of this aircraft change, the scheduled Auckland/Nadi departure time will be as published; however, the Nadi/Auckland service will be delayed until later that afternoon," it said.
