American Airlines Christmas Eve Flight Delays Resolved After Hour-Long Grounding Caused by Technical Glitch

A technical glitch caused American Airlines to ground flights for an hour on Christmas Eve, delaying thousands of passengers during one of the busiest travel periods of the year. Operations resumed quickly, sparing the airline from a larger crisis during peak holiday travel.

Flights Resume After Ground Halt

On Tuesday, American Airlines announced that flights have resumed following an hour-long ground halt caused by a technical issue. The ground stop had disrupted travel for thousands of people on Christmas Eve, which is often one of the busiest periods of the year.

According to the airline, DXC Technology, an operating system vendor, was to blame for the momentary disruption to the carrier's aircraft operations due to a hardware fault with its network. Investing.com reports.

The relatively short outage means American will probably escape a full-scale collapse that might spread for days during the high holiday travel season, even if customers were still clamoring for news about their delayed flights.

According to statistics from aviation analytics firm Cirium, out of 3,901 flights scheduled worldwide on Tuesday, 19 had to be canceled.

Data Shows Widespread Delays and Cancellations

Nevertheless, as far as Cirium is concerned, just 37% of the flights have taken off on time and 36% have landed on time.

"Not a good start to Christmas Eve travel as current flight is grounded and Captain cannot provide ETA on resolution from system outage and/or paperwork error at national level. Will make connections or refunds more complicated too," a user wrote, tagging American Airlines on X.

After carriers experienced a worldwide tech outage associated with Microsoft's Azure cloud platform and a software problem at cybersecurity firm CrowdStrike earlier this year, Tuesday's hiccup marks the most recent technical setback.

Delta Air Lines lost at least $500 million due to the disruption.

Airline Industry Struggles With Recurring Glitches

Two years ago, during the holidays, Southwest Airlines had a system failure that caused 16,900 flights to be canceled and 2 million customers to be stranded. Ultimately, it was fined $140 million, the highest civil penalty ever levied for interfering with travel plans.

According to Ken Quinn, a partner at the law firm Clyde & Co., airlines have improved their cybersecurity and operational software systems. However, he notes that the recent failures are not completely unexpected, considering the flight attendants' departure during the pandemic.

Every day, American Airlines flies thousands of passengers to 350+ locations in 60+ countries.

Technical Issue Highlights Weight and Balance Concerns

Reuters was directed to the airline by the US Federal Aviation Administration in a statement issued on Tuesday, which reiterated that the company had reported a technical issue.

According to former American Airlines executive and current consulting firm owner Robert Mann, the problem stemmed from the company's automated system's failure to legally dispatch each flight with the proper weight and balance data, which includes the mass of passengers, bags, cargo, and the overall center of gravity.

He speculated that the management system might have failed to load the necessary data to calculate the engine power needs and achieve a successful takeoff.

Dallas-Fort Worth, another American hub, was also seeing delays in arrivals and departures, which the airline said were caused by bad weather.

In the run-up to the holidays, TSA anticipates screening 40 million travelers, a new high.
