"If you get that 8 am flight, very often the plane was already there from overnight, so you're on and you're out right on time," Sognonvi told The Points Guy.
Early starts may sound impossible with kids but Sognonvi said this also meant airports are less crowded, making it less stressful.
The second piece of crucial advice was avoiding checked baggage when possible to avoid long waits at luggage carousels.
Standing for half an hour or longer with fellow fliers can be difficult for children after sitting on a flight.
"It saves so much time because you don't have to wait around for the luggage and you don't have to worry about lost luggage," she said.
Further to Sognonvi's tips, travel TV host Samantha Brown said many parents also make the mistake of boarding flights first with their children, reported the Sun.
It may seem appealing to get on the plane while it's quiet, however, Brown said waiting at the gate is far easier than waiting in the plane seats while everyone else boards around you.
