Most of the people would not bother to register any formal complaints for a delayed flight, they would just make noises in the airport at the airline staff, which usually results in nothing more than a high BP.

When Go Air flight for cancelled and no reasons were given Mr. Yogesh Kumar filed a petition which resulted in getting compensation for all passengers on that flight.

I hope business are responsible enough to provide added facilities when there is a delay for whatever reason and by doing so they will show their loyalty towards their customers which will go a long way to make their business very successful.
