The Federal Aviation Administration (FAA) was scrambling to correct a computer glitch early on Wednesday. The impacted system provides critical safety information to pilots. The malfunction may lead to the grounding of many US flights.
Las Vegas’s Harry Reid International Airport was among the two airports highlighted in a CNN report on Wednesday morning about the computer system failure.
As of 4:45 am PT on Wednesday, delays at Harry Reid totaled 151 flights, FlightAware, an online flight tracking service, reported. There were eight cancellations as of early morning.
There is no predicted time for the system to be operating properly.
Nationally, some airlines released statements their flights could be delayed. The trade association for US carriers, Airlines for America, said the glitch was “causing significant operational delays,” CNN reported.
“Operations across the National Airspace System are affected,” the FAA said in its own statement.
The FAA is experiencing an outage that is impacting the update of NOTAMS. All flights are unable to be released at this time,” the FAA added.
Cleared Update No. 2 for all stakeholders: ⁰⁰The FAA is still working to fully restore the Notice to Air Missions system following an outage. ⁰⁰While some functions are beginning to come back on line, National Airspace System operations remain limited.

System Explained
The impacted computer system is called Notice to Air Missions (NOTAM). It provides information on flight hazards and real-time restrictions to pilots, ABC News reported.
As of 7:15 am ET on Wednesday, the FAA announced that “some functions are beginning to come back on line,” CNN quoted the government agency.
The FAA was repopulating the system as of about 7 am ET on Wednesday.
Passengers were encouraged to check with their airlines to see if flights are delayed.
Many visitors to Las Vegas casinos fly into the city or head back home via Harry Reid Airport.
Prior Delays
Wednesday’s glitch follows weather-related delays and cancellations at Harry Reid on Tuesday.
Hundreds of flights were delayed or canceled at the airport due to heavy rain.
Some 323 flights were delayed on Tuesday afternoon, FlightAware data showed. Some 29 flights were canceled.
Delays and cancellations this week follow massive delays between Christmas and New Year’s Day.
Thousands of passengers at Harry Reid Airport were delayed or stranded waiting for flights during the holiday week. The two-week period is traditionally a popular time to travel, only making the disruptions more severe.
Many stranded airline passengers last month opted to rent a car and drove to their destinations. That led to a scarcity of rental cars in many locations. Prices also escalated.
The US airports which saw the most cancellations during the holiday travel period included Atlanta’s Hartsfield-Jackson International Airport, Denver International Airport, Baltimore Washington International Thurgood Marshall Airport, and Chicago Midway International Airport, CNN said.
Southwest Airlines was highlighted for its large number of delayed or cancelled flights at the end of last month.
Southwest is the dominant carrier at Harry Reid Airport. More than 17.2 million passengers flew into and out of Las Vegas on a Southwest plane between October 2021 and last September, according to US Bureau of Transportation Statistics data.
Airlines initially blamed the holiday delays on winter storms impacting much of the nation between Christmas and New Year’s Day. But it was later revealed that other causes also led to the disruptions.
