More than 1,700 Allegiant Air passengers traveling between the mainland and Honolulu were delayed over the weekend and through tonight for as many as two days due to airplane mechanical issues.

The low-cost carrier, which connects travelers primarily from secondary cities to leisure markets, said today that the last of the affected nine flights was expected to arrive early Tuesday morning in Las Vegas — about 52 hours late.

That flight — Honolulu to Las Vegas — was delayed again Monday night from its rescheduled 5:50 p.m. departure when the aircraft that was going to be used didn’t pass mechanical inspection. Another plane was readied and the flight finally took off at 6:35 p.m. It was originally supposed to leave at 2:45 p.m. Saturday. The 223-seat Boeing 757 was scheduled to carry 173 passengers and the airline is estimating it will arrive in Las Vegas at 3:21 a.m. Tuesday. 

Other flights delayed from Honolulu were bound for Fresno, Calif; Phoenix; Boise, Idaho; and Stockton, Calif. Inbound flights affected were from Spokane, Wash.; Stockton; Boise and Phoenix.

Allegiant spokesman Brian Davis said the delays were due to unrelated mechanical issues involving three Boeing 757s.

Inconvenienced passengers who live more than 50 miles from the airport were provided hotel rooms, meal vouchers and discounts of $50 to $200 off of future flights, Davis said.

“To the best of our knowledge, all the mechanical issues have been resolved at this point,” Davis said this afternoon. “We anticipate a normal schedule moving forward.”

Las Vegas-based Allegiant said all affected passengers have the option to reschedule or cancel their ticket at no additional cost. Passengers with questions are being asked to call 702-853-4625 and press 1 for a spokesperson. 

“We never want to delay or inconvenience our customers, but the safety of our passengers and crew is our No. 1 priority,” Allegiant said in a statement.
