Expressing her experience of portraying the role of Bhanot, Kapoor wrote, "Portraying a young girl from Bombay who saved the lives of the 359 passengers onboard Pan AM Flight 73 was not only challenging but also a great honour."
"As the movie completes its 4th anniversary, I would want people to recall how fear gave courage to the young Neerja Bhanot," she further wrote.
The 34-year-old actor also shared a picture of herself with Neerja Bhanot's mother.
"She was the true icon of bravery, strength, and sacrifice for our country. She continues to be an inspiration to everyone. #4YearsOfNeerja" read another tweet from Kapoor.
