I did a mistake that is I came out of the exit gate and I had to wait for almost 5 hours out side the entry gate, no shops were open and I was hungry, I had water with myself thats all.
The night seems to be tough but I had to be awake since I had my another flight at 6.30 am for Guwahati.
As soon as I boarded I went for a sleep and It was the first time that I haven't seen my flight taking off and landing. I wasn't able to open my eyes for a second.
I book rapido as soon as I arrived at Guwahati Airport to Railway station.
