Kamra on Thursday took to Twitter, where he shared a photograph of himself holding a placard which read: "Arnab I just want to say I am not sorry."
He captioned the image: "Sorry for not being sorry."
Kamra was banned by Indigo, Air India and Spice Jet after he allegedly heckled journalist Arnab Goswami in a flight from Mumbai to Lucknow on Tuesday.
The comedian had shared a video on Twitter where he could be heard asking his co-passenger Arnab Goswami: "Viewers today want to know if Arnab is a coward or a nationalist. Arnab, this is for national interest. I am part of the tukde-tukde narrative. You should deflate me. You should take the enemy of the states down.You can watch the video here;
"You should make sure that the country is in safe hands of Narendra Modi. You should fight against dynasts like Rahul Gandhi, who I support, on 10 Tughlaq Lane. Arnab, you should have a reply, Arnab. Arnab, are you a coward or are you a journalist? Are you a coward or are you a journalist or a nationalist? Who are you, Arnab?"
However, Arnab Goswami chose to remain quiet and did not answer back.
Earlier, Kamra alleged that Goswami has called him mentally unstable. He tweeted: "Met Arnab Goswami on a flight and gave him a monologue about his 'journalism'. All he did was call me mentally unstable and after sometime I had no choice but to return to my seat. The entire flight I'll keep pretending to use the loo just to tell him he's piece of SH*T. F*CK Arnab".
On Tuesday evening, Indigo issued a statement via Twitter where they announced that they are banning Kunal Kamra for six months for his in-flight behaviour. SpiceJet and GoAir have followed suit.
