The miraculous survival of a passenger who escaped moments after his Air India flight crashed, killing all others on board, has sparked debate over whether his seat, 11A, is the safest on a plane.

However, aviation experts say that determining the safest seat is not so simple, as aircraft configurations vary significantly and survival usually depends on a complex combination of factors.

“Each accident is different, and it is impossible to predict survivability based on seat location,” Mitchell Fox, a director at the Flight Safety Foundation, a US-based nonprofit, said.

Ramesh Viswash Kumar, who was seated in 11A, recounted how his proximity to an emergency exit on the London-bound Boeing 787 Dreamliner that crashed on Thursday allowed him to walk to safety.

Sitting next to an exit door may increase a person’s chances of survival in a crash. However, experts say that the specific seat number, such as 11A, is not universally the safest, as aircraft can have numerous different layouts.

“In this particular instance, because the passenger was sitting adjacent to the emergency exit, this was obviously the safest seat on the day,” Ron Bartsch, chairman at Sydney-based AvLaw Aviation Consulting, said.

“But it’s not always 11A, it’s just 11A on this configuration of the Boeing 787.”

A Popular Mechanics study of crashes since 1971, published in 2007, found that passengers seated towards the back of the plane had better survival odds. Some experts also suggest the wing section offers more stability.

Sitting next to an exit door, like Mr Kumar, gives you an opportunity to be one of the first out of the plane, although some exits do not function after a crash. The opposite side of the plane was blocked by the wall of a building it crashed into, he said.

In January 2024, a panel missing several bolts blew off the side of a Boeing 737 MAX mid-flight, creating a gaping hole and damaging the adjacent seat. Fortunately, no one was seated there at the time, and the incident resulted in no fatalities.

Sitting by the aisle might offer you a speedier escape but it increases the likelihood of being hit in the head by luggage falling out of the overhead bins, which is a much more common occurrence than major crashes.

The importance of safety briefings

Paying attention to the safety briefing at the start of your flight – often dismissed as routine – is likely the best way to improve your chances of survival, experts say.

Disciplined compliance with cabin crew evacuation advice, including leaving bags behind, was a key factor in saving the lives of all 379 passengers and crew aboard a Japan Airlines flight in January 2024.

The Airbus A350 aircraft had collided with a Coast Guard plane at Tokyo’s Haneda Airport, killing five of the six crew members on the smaller aircraft.

Safety briefings typically cover critical instructions such as how to fasten your seatbelt securely, adopt the correct brace position and plan your evacuation route.

A common tip is to count the number of rows between your seat and the nearest exit – vital knowledge if the cabin fills with smoke and visibility is low.

Despite disasters such as the Air India crash, plane designs have evolved to increase the likelihood of passengers walking away from a rare plane accident, Mr Fox said.

These include floor path lighting, fire detection and extinguishers, less flammable cabin materials and improved access to emergency exits.

“There have been remarkable advancements in airplane cabin design that have improved the survivability of accidents on or near the ground,” Mr Fox said.
