How a ground staff walkout disrupted Air India operations within hours

Hundreds of passengers travelling through Mumbai airport on Monday found themselves caught in aviation disruption that unfolded with remarkable speed.

Flights landed on time but passengers remained trapped inside aircraft for nearly an hour. Departure schedules slipped. Checked-in baggage stopped moving. Boarding gates became crowded with confused travellers waiting for updates that never came.

At the centre of the disruption was not bad weather, a technical fault or an air traffic issue. Instead, operations across Air India and Air India Express were hit by a protest staged by employees of AI Airport Services Limited (AIASL), a government-owned ground handling company operating at Mumbai’s Chhatrapati Shivaji Maharaj International Airport.

Within hours, the industrial action had disrupted at least 15 flights and highlighted how vulnerable airline operations remain to breakdowns in ground support services.

Flight operations slowed almost immediately

The disruption began after a section of AIASL employees staged what the company later described as a “silent morcha” over salary hikes and other demands.

Ground handling staff play a critical operational role at airports. They manage aircraft turnaround activities including:

• Passenger deplaning support
• Baggage unloading and transfer
• Aircraft servicing
• Boarding operations
• Ramp coordination

When those operations slow down or stop, aircraft cannot be processed efficiently after landing or prepared quickly for departure.

That is precisely what unfolded in Mumbai.

Passengers arriving on multiple Air India flights reported remaining inside aircraft for extended periods after landing because ground staff were unavailable to complete arrival procedures.

One affected passenger, Sujit Dilip, told News18 that his Air India flight from Hyderabad landed around 11.45 am, but passengers remained onboard until nearly 1 pm.

“We landed at 11.45 am and had to remain inside the aircraft till around 1 pm,” he said. “Even after that, there was no clarity on where to collect our baggage from and I was only able to get mine around 2 pm.”

Dilip said he missed a scheduled business meeting in Mumbai because of the delay.

The disruption quickly spread beyond arriving flights.

Departures also faced cascading delays

The operational impact was not limited to aircraft waiting for deplaning support.

Outgoing services also faced significant delays as ground operations slowed across terminals.

Among the affected flights was Air India flight AI 431 from Mumbai to Dehradun, scheduled to depart at 12.10 pm.

Passengers reported waiting at the boarding gate for hours without clear communication regarding departure timing.

According to News18, passenger Gajendra Verma, an 80-year-old retired government employee, said travellers had been waiting since 11 am despite scheduled boarding beginning shortly afterwards.

The flight reportedly had not departed even by 3.30 pm.

At least 15 outgoing flights were delayed by up to two hours during the disruption, according to reports.

The delays exposed the highly interconnected nature of airport operations, where even a temporary interruption in staffing can create rapid cascading effects across arrivals, departures and baggage systems.

Air India confirms operational disruption

Following mounting passenger complaints on social media and inside terminals, Air India issued a statement acknowledging the disruption.

The airline said industrial action by employees of a third-party ground handling agency had affected operations at Mumbai airport.

“Industrial action by employees of a third-party ground handling agency at Mumbai airport is impacting the operations of Air India Express and Air India,” the airline said.

The carrier added that airport teams were working with stakeholders to restore normal operations and minimise inconvenience to passengers.

However, the statement did not specify the precise cause of the workers’ protest or provide a timeline for full operational recovery.

The disruption also highlighted the operational dependency airlines have on outsourced or third-party airport services, particularly at high-traffic hubs such as Mumbai.

Why ground handling staff are critical to aviation

Ground handling operations rarely attract public attention unless something goes wrong.

Yet these workers form one of the most essential components of airline operations.

Ground handling teams are responsible for coordinating aircraft movement on the ground and ensuring flights are processed efficiently between arrival and departure.

Their responsibilities typically include:

• Parking aircraft at arrival bays
• Operating aerobridges and passenger stairs
• Loading and unloading baggage
• Cabin cleaning
• Aircraft servicing support
• Pushback and turnaround coordination

Without these processes functioning smoothly, airlines cannot maintain schedules.

At busy airports such as Mumbai, where passenger traffic exceeds 50 million annually, disruptions involving ground handling services can escalate rapidly because of tightly packed flight schedules and limited turnaround windows.

Even a short work stoppage can create delays that ripple through the system for hours.

AIASL resumes operations after talks with staff

Later in the day, AIASL said employees had returned to work after management assured them that their concerns would be reviewed.

According to the company, protesting employees submitted their demands in writing following discussions with management.

AIASL Chief Executive Rambabu told reporters that staff had resumed duties after being assured the company would examine their requests within existing policy frameworks.

“There was a silent morcha by a certain section of employees, and we requested them to give us in writing their demands for discussion,” he said.

“They have been kind enough to go back and join work.”

The company did not publicly disclose the full list of employee demands beyond references to salary-related concerns and other issues.

A disruption with industry-wide implications

The incident also underscored the scale of AIASL’s operational footprint within Indian aviation.

The company handles ground services for nearly 80 airlines, including:

• flydubai
• Saudia
• Oman Air
• SalamAir

According to company data cited by News18:

• AIASL operates across 84 airports
• The company manages around 650 flights daily
• It employs nearly 20,000 workers

That operational scale means even localised disruptions can potentially affect multiple airlines and airports if not resolved quickly.

For airlines, the episode serves as another reminder that operational resilience depends not only on aircraft and scheduling, but also on workforce stability across airport ecosystems.

Pressure on airlines continues to grow

The Mumbai disruption comes at a difficult time for airlines already managing rising operational pressures.

Fuel prices remain elevated, geopolitical tensions continue affecting aviation markets globally and several airlines are simultaneously dealing with fleet constraints and cost pressures.

For Air India specifically, the incident arrives amid a major transformation programme under the Tata Group, which includes fleet expansion, network restructuring and operational modernisation.

While Monday’s disruption was not directly caused by the airline itself, the incident still affected passenger experience and operational reliability, two areas the carrier has been attempting to improve aggressively.

For passengers stranded onboard aircraft or waiting hours for baggage, the distinction between airline operations and third-party ground services mattered little.

The disruption demonstrated how quickly airport operations can unravel when one critical part of the aviation chain stops functioning.

And in one of the world’s busiest aviation markets, even a brief walkout was enough to bring parts of the system to a near standstill within hours.
