Are you flying for the first time? Be aware that this is one of the safest means of transport there is :D
To ensure a quiet journey, be sure to be aware of all information about your flight, available on your ticket, such as the correct airport, airline, date and time of flight and boarding. Schedule to arrive at the airport 1 hour before national flights and 2 hours before international flights according to the departure time. Under normal conditions, the plane actually takes off at the scheduled time of the ticket and closes the boarding a few minutes before. So don't be late! The airline can't - and won't - wait for the late passengers.
Upon arriving at the airport, the first thing you should do is to search the airline counter to do the boarding procedure, known as check-in. That's when you identify yourself to the airline and you can dispatch your luggage, if any. The agents will inform you which is the boarding gate and may resolve any doubts that may arise. Please report to the boarding gate at the scheduled time and have a good trip!
