I booked a flight from chennai to bangalore which is supposed to be a 50-55mins flight. Already flight has got delayed for 90 mins. Give me a reason why I should pay 6000 and still bear all this.
Moreover, I will reach around 12:15 to bangalore, instead of 10:55. It will be so late at night and I will have to face issues considering that I have work tomorrow.
I am not happy with this. I hope you act against this.
