When you are a first timer for flights it's very exciting for you and the time passes exploring the airport. But for me the first experience was something that my time pass was just running from the gate allotted in the ticket to the opposite direction where the announcement is being done and if you have travelled from Indra Gandhi International Airport that to T-3 then you would know how long the you to walk from one end to another.
But if you see the small domestic airports in India, they are really difficult to pass your time. So, I take few things with me for long hours flight and for the waiting area is books or novels being an avid reader I have novel with me in airport. I have my coffee sometimes. Or food in the airport's food court. The crazy thing I did was in the conveyor belt jumping and making boomerangs after four hours long security check. Even if you are sitting there observe people it's actually good see people running and tripping in the conveyor belt.
