American Airlines ‘glitch’ allows all pilots to take vacation over Christmas week

A computer error has allowed too many pilots at American Airlines to schedule time off during the upcoming Christmas season, creating a potential pilot shortage for what is expected to be one of the busiest holidays in years for the airline industry.

The Fort Worth-based carrier said it hopes to avoid canceling any flights during the holiday period by calling in reserve pilots and offering other pilots 150% of their salaries to return to the cockpits during the time they have been approved to be on vacation.

“We are working diligently to address the issue and expect to avoid cancellations this holiday season,” the airline said in a statement.

Airline representatives declined to say how many of the carrier’s 15,000 pilots were allowed to take time off for the holiday. But the number was high enough that the carrier had to quickly adopt several new measures to keep its holiday flights on schedule.

During the Thanksgiving holiday, an estimated 28.5 million passengers flew on U.S.-based carriers, a 3% increase over the same time in 2016. The airline industry is bracing for an even bigger surge in travelers during the Christmas holiday.

The computer that manages payroll and vacation schedules at American Airlines is separate from the system that manages passenger reservations. Still, industry experts say the increased complexity of airline computer systems is to blame for a growing number of glitches that have recently grounded airplanes and posted ultra-cheap airfares.

In July 2015, United Airlines requested a ground stop for nearly 90 minutes for all U.S. departures. The airline blamed the problem on a failed computer network router that disrupted its reservation system.

In 2014, Delta Air Lines reported computer problems that produced super-cheap fares, while Alaska Airlines had a computer glitch that offered a promotional deal that expired before passengers could book it.

American Airlines had to ground flights for more than two hours because of a malfunctioning computer in April 2013.

Lost Tool Found in Qantas A380 After 34 Flights

An Australian Transportation Safety Bureau (ATSB) investigation recently revealed that a Qantas A380 operated 34 flights with a 1.25-meter nylon tool lodged in one of its engines.

This turning tool, used during borescope inspections to rotate the intermediate-pressure compressor, was left behind during scheduled maintenance at Los Angeles on December 6, 2023. It remained inside the engine until it was discovered by maintenance staff during a subsequent check at Los Angeles on January 1, 2024.

The ATSB report highlights two critical lapses. First, maintenance engineers failed to notice the tool during final checks for foreign objects after the borescope inspection. Second, the lost tool procedure was not activated when the tool was identified as missing.

The certifying engineer ultimately cleared the aircraft for service without accounting for the misplaced tool. During the time qantas films the tool was inside, the A380 completed 34 flight cycles, accumulating nearly 294 hours without any noticeable effect on engine performance.

Although the tool was deformed by high-energy airflow within the engine, there was no reported damage to the engine itself. ATSB Chief Commissioner Angus Mitchell commented.

“This incident underscores the importance of following established maintenance protocols. Engineers missed the tool during foreign object checks, and the required lost tool procedure wasn’t started after realizing the tool was missing.”

Following the investigation, the airline issued a safety directive, urging all engineering and tool storage teams to adhere strictly to these protocols to prevent similar incidents in the future.

A qantas spokesperson stated, “While the tool didn’t impact engine performance, we take this incident very seriously. It is critical to follow the correct lost tool procedures.”
