The airport gave an update through its Twitter account at 7:53 a.m. Wednesday, saying an earlier ground stop had been canceled and that American's computers were back up and running.
The FAA said American's systems at other airports, including at Pittsburgh International Airport, are not having issues.
"We are trying to fix it as quickly as possible", airline spokeswoman Katie Cody said.
Travelers were reporting long check-in lines due to the downed systems. "We are continuing to check in passengers manually".
The outage affected only American Airlines passengers. Here's the check in line.
American spokeswoman Victoria Lupica said the airport's division of aviation had a planned maintenance power outage from 1 to 4 a.m.
A McCarran spokesperson said American Airlines flight 0073 was on the runway about to depart to Los Angeles, but it never got off the ground.
Cody says passengers can ease the process if they don't have to check bags and can print out or have their boarding passes on their mobile devices.
