Ms Sanon was travelling to Delhi last week when the man seated beside her and her mother started using an iPhone projector to watch Hindi blockbuster "Dilwale".
The $15 million movie, which sees Ms Sanon star alongside mega-star Shah Rukh Khan, had only been released in cinemas 10 days ago.
"Someone watchin pirated version of Dilwale in front of me on phone in the flight! Annoyed!! #SayNoToPiracy," the 25-year-old posted on Twitter.
The tweet, which has been liked almost 3,000 times, was accompanied by a photo showing the passenger watching the movie. It also included an angry emoji face.
Shortly afterwards she tweeted again.
"Sad to c the hardwork of so many ppl bein watched in such pathetic quality! Pls enjoy films in cinemas #SayNoToPiracy," Ms Sanon wrote.
It was accompanied by another picture of the passenger, who appeared to be enjoying the movie.
A third tweet followed, in response to a user who said that watching pirated movies was a criminal offence.
"Yup..told him politely tht he would enjoy the film more in a theatre. but he was busy showin off his projector!," she wrote, this time including two angry emoji faces.
