A nationwide computer system outage with Allegiant Air forced the Las Vegas-based carrier to take on long lines to check customers in on Monday.
McCarran Airport Public Information Officer Christine Crews confirmed the outage. In addition, Allegiant's official Twitter page also indicated the outage through replies to customers.
"Sorry for any disruptions as we work through a system outage. We appreciate your patience," one tweet reply read.
A check of Allegiant flights on the McCarran Airport website showed seven scheduled departures as delayed late Monday morning.
A post to the airline's official Twitter page about 1 p.m. said all systems were back online.
Crews noted Allegiant ticket agents were forced to check passengers in manually.
