The national carrier has decided to prepare a "no-fly" list of unruly passengers, say sources.
When Mr Gaikwad's flight from Pune landed in Delhi around 10.30 am, he refused to get off the plane for nearly an hour.
The lawmaker was reportedly upset about travelling economy when he has an open business class ticket that he is entitled to as a member of Parliament.
The morning flight he took was all-economy, but that failed to mollify him.
As he refused to budge or let the staff prepare the plane for its next flight, Customer Relations Manager Shiv kumar was called in. "I told him you are a senior person and asked him to sit down and BP mat badao (control your blood pressure). I said I am an MP, don't raise your voice. He said 'what MP? I will talk to (Prime Minister Narendra) Modi', so I hit him. I am not here to take abuse...I am not from the BJP," the lawmaker shrugged.
Mr Gaikwad, 57, is a first-time lawmaker from Maharashtra and no stranger to controversy. In 2014, he was among a group of Sena members who tried to force-feed a Muslim employee of Maharashtra Sadan during Ramzan, complaining about bad food.
The MP has been skewered on social media and by various parties including ally BJP.
"Elected representatives need to respect people who are doing their job, irrespective of whether the Air India man was rude," said BJP leader Shaina NC.
