While going on a vacation where all the travel arrangements have been done, you wouldn’t want to be late for your flight or not have enough time to get through the airport lines before the gates closed, causing you to miss it. These issues arose as a result of your inability to determine how early to be at the airport for your flight. Given the situation, it would be challenging to forecast when one should be at the airport gates because there are many varying aspects involved.  Still, just a few things can be taken into account when making a decision. Like how big and crowded is the airport of departure? How far is your home from the airport? Does the nation you are visiting demand heightened security screening? Is it a busy day or time of year? Are you travelling with a sizable group or possibly young children?
