Mechanical issues on two of Hawaiian Airlines’ aircraft left 180 passengers stranded overnight Monday in Los Angeles and delayed their scheduled arrival in Honolulu for more than 32 hours.

Passengers on a nonstop flight originally scheduled to fly from Las Vegas to Honolulu and land at 12:15 p.m. Monday arrived Tuesday around 8:35 p.m. from Los Angeles.

The lengthy delay stemmed from mechanical issues on both the original Airbus A333-200 aircraft coming out of Las Vegas and the replacement A330 that was supposed to transport passengers from Los Angeles after the aircraft was diverted there and passengers were forced to spend the night.

“(Monday’s) aircraft needed a new part for the air conditioning system. We moved the flight to the new aircraft (Tuesday) morning. Unfortunately, that incurred a separate maintenance issue (a faulty sensor light) with the prime computer. They are separate issues, and uncommon parts, which is why they need to be flown in,” said Hawaiian spokeswoman Alison Croyle in an email Tuesday morning.

Ann Botticelli, another Hawaiian spokeswoman, said 104 passengers that were connecting in Honolulu to neighbor islands were placed on other airlines on Monday. The remaining 180 passengers went out on a 6 p.m. flight Tuesday that was a regularly scheduled flight from Los Angeles to Honolulu. Those passengers were joined by 132 passengers who were originally scheduled to depart on that flight.

The remaining 151 passengers unable to board as scheduled at 6 p.m. were given $100 travel vouchers and were due to leave at 11:30 p.m. Los Angeles time on Tuesday and arrive at 2:25 a.m. Wednesday. Another 15 passengers scheduled for that flight were reaccommodated to Maui on an American Airlines flight. Botticelli said the passengers who were originally booked to board that 6 p.m. flight were selected on a first-come, first-served basis.

Botticelli said Monday the aircraft was 20 minutes off the West Coast when the pilot noticed that an indicator light showed a possible problem with the aircraft’s air conditioning system. The pilot decided to divert to Los Angeles where it landed at 10:30 a.m.

The airplane was initially scheduled to leave L.A. at 1 p.m. Monday, but Botticelli said an airline part needed replacement and the part needed to be brought in from Minneapolis.

Passengers were fed, put up in hotel rooms and given a $300 travel credit, she said.
