Allegiant Airlines passengers arriving this morning at airports across the country were in for a rude awakening as a temporary outage of the airline's computerized check-in system forced delays and long lines .
The Las Vegas-based carrier diagnosed the issue at 5:25 a.m. local time, according to Allegiant spokesman Micah Lillard. It took Allegiant until around 7:30 a.m. to fix the problem.
By then the damage was already done.
At McCarran International Airport, lines at the Allegiant ticket counter saw an "incredible increase," according to airport spokeswoman Christine Crews. Similar delays were reported at other airports, including Orlando-Sanford International Airport.
McCarran staff pitched in to help the airline manage the backup of travelers. Allegiant's website, which tracks problems reported by passengers, showed around 112 complaints from the time the outage started to around 9:30 a.m. The company's website also was down for most of the outage but has since been fixed.
Lines and delays have since dropped off, Crews said. Five Allegiant departures from Las Vegas were reported delayed as of 9:30 a.m., according to the McCarran website.
It's not yet known what caused the outage, or how many customers and flights were affected.
