Allegiant tells fliers to arrive 3 hours early due to wait for airport processing

LAS VEGAS (KSNV) — Allegiant is asking passengers to arrive very early for their flights on Wednesday.

The airline says a "recent system update" has led to delays in airport processing, and fliers should come to the airport at least three hours before their scheduled departure.

Passengers flying out Wednesday, Aug. 23, have to go to the Allegiant ticket counter, prior to going through security, to get updated boarding passes.

Any boarding pass generated on Aug. 22 is no longer valid due to the system update, according to Allegiant.

All fees associated with printing boarding passes at the airport will be waived.

Allegiant is headquartered in Las Vegas, and Harry Reid International Airport is its second-busiest domestic market.
