Near Death Experience on Jaipur - Kolkata Indigo flight 6E-2

Had a horrible experience aboard Indigo airline while flying from Jaipur to Kolkata last week. I was on-board Indigo 6E-237 and half-an-hour before landing in Kolkata smoke started filling the cabin. This smoke was coming from AC vents and everyone aboard the flight was terrified as this drama unfolded mid-air ruling out any possibility to land any time soon. Everyone was afraid whether the flight would or wouldn't land. It almost felt as if we were sitting in the middle of a pyre of burning plastic and metal. That smoke was so horrible that babies started crying and passengers started murmuring and started throwing nervous glances at each other. Panic was written all over everyone’s face. As the flight landed, I asked a flight attendant to help me get out of the flight but it seems that the crew on board froze. I beg to question the safety regulations followed by Indigo and its crew members. With each moment that passed, everyone grew more and more afraid as smoke completely engulfed the cabin. With little help or information coming from the crew, everyone expected the worse. I swear I will think twice before taking an Indigo flight and will also urge everyone to reconsider Indigo. While it can be written off as a stray incident, the reality is that their aircraft have encountered issues in the recent past.
