When it comes to one particular travel issue, everyone has an opinion. Airports and airlines have strong suggestions for it, and there is no simple answer.

How early do you need to get to the airport to make your flight?

In the end, it all gets down to time of day, the airport, the country and whether you have bags to check. It also depends on if you are traveling by yourself or with an entire family.

My advice is to have a minimum of 75 minutes ahead, if you’re traveling by yourself with no bags on a domestic flight. Then add 40 minutes for baggage, another 40 minutes for travel companions, and another 40 minutes for an international flight.

And in my book, these suggested times apply even if you have TSA PreCheck, because those lanes can often be closed during peak travel times.
