RALEIGH, N.C. — A power outage early Friday morning in Terminal 2 at the Raleigh-Durham International Airport has caused major delays for many passengers.

Around 11:30 a.m. RDU provided an update saying, "Contractors have replaced the 1600 amp circuit breaker to fully restore power to all systems in Terminal 2." 

RDU said travelers should continue to expect delays, however, due to lingering impacts of the outage.

Just after 4 a.m. the airport's Twitter account posted a message saying, "We are experiencing major power outages in Terminal 2 that are impacting our ability to serve passengers. Terminal 1 is unaffected." Passengers are encouraged to check their flight status online before coming to the airport.

Passengers quickly took to social media, saying hundreds of people were stuck in line waiting to clear TSA and other checkpoints. Due to the outage, TSA officials had to begin performing manual pat downs and bag searches for each passenger before allowing them to clear security.

"The line from the back is at least 2.5 hours long," one passenger wrote on Twitter in reference to the backup at TSA. Video from another passenger showed lines wrapped around the inside of the building multiple times.

Despite power being restored to the airport's systems, long lines and extensive delays are expected to continue throughout the day.

Prior to coming to the airport, officials say passengers should check and continuely monitor their flight status for any possible delays or cancellations.
