Early time Trip Ticket

I usually get first trip plane ticket in Cebu pacific airlines.I have three reasons: I am not in a hurry going to the airport .Then, It is not too risk to travel from Laguna to Manila.I will arrived home early.My routine is I travel from Laguna to Airport terminal in the evening.I sleep in the airport but of course I have to eat my dinner first because it is expensive to buy food inside the terminal.
