Thakur was allegedly so upset with the 1 hour 30 minute flight that she did not get off the plane for a while after it landed. She also told reporters, 

The airline staff does not behave properly with passengers. They did not give me the booked seat. I asked them to show the rules. I called the director and lodged a complaint with him.
