Summary: A handwritten bomb threat found in the toilet of IndiGo flight 6E3074 on February 14, 2026 led to passenger deboarding and isolation checks at Kolkata's Netaji Subhas Chandra Bose International Airport; no injuries were reported.

An IndiGo bomb threat disrupted operations at Kolkata’s Netaji Subhas Chandra Bose International Airport on the morning of February 14, 2026 when a handwritten note alleging the presence of a bomb was found aboard flight 6E3074 bound for Shillong.

What happened on flight 6E3074

Crew members discovered the handwritten threat inside the aircraft toilet during boarding. The message allegedly claimed a bomb was on board, prompting immediate safety measures by airline and airport personnel and the deboarding of all passengers.

Immediate response and security checks

After passengers were taken off the aircraft, officials moved the plane to an isolation bay for a thorough security sweep. Airport authorities and the airline coordinated to inform the relevant agencies and to carry out the required checks before the aircraft could be cleared.

“As always, safety and security of our customers, crew, and aircraft are our topmost priorities,”

An IndiGo spokesperson confirmed the airline informed authorities and that security procedures were followed. The incident was resolved with no casualties or injuries reported.

Impact on passengers and schedules

The discovery disrupted boarding and caused delays for travellers scheduled on the flight. Passengers were left stranded while authorities completed inspections; airlines and airports often reroute, reschedule or accommodate affected travellers depending on the outcome of such security checks.

  • Deboarding and waiting for clearance can add several hours to journey times
  • Subsequent flights may face knock-on delays or cancellations
  • Passengers may need to rebook or make alternative travel arrangements

Context: repeated threats and security vigilance

This is not an isolated event for IndiGo in recent weeks. On January 23, 2026, IndiGo flight 6E 2608 from Delhi to Pune also received a bomb threat that prompted an emergency response. Such incidents underscore increasing attention on aviation security and the need for rapid coordination between airlines and authorities.

Shillong’s tourism appeal and growing connectivity

Shillong, often called the “Scotland of the East,” draws visitors for its green landscapes, Umiam Lake, Elephant Falls and the Mawphlang Sacred Forest. As flights from cities like Kolkata have improved access, the hill station’s rising popularity makes secure, reliable air links increasingly important for both domestic and international visitors.

What this means for travellers

So what? Incidents like the Feb. 14 bomb threat remind passengers to expect possible delays and to monitor flight status closely before travel. Airlines and airports will continue to prioritise safety, meaning that while security checks may inconvenience travellers, they are essential to keeping flights and destinations like Shillong secure and accessible.
