If you are boarding a flight for the first time, get to the airport 2 hours before the departure. Your ticket will have the information of your terminal, so keep that in check. The purpose of getting to the airport earlier is to learn your way through it. There are information booths all over the place you can find them, and they will let you know what you should be doing. All you have to do is keep your baggage in check, for that you can use a trolley.
