I always drive 2 hours before my flight but I give myself another hour for the arrival parking lot cuz you have to check into the parking lot park your car that usually takes anywhere from 5 210 minutes for the bus to pick you up then you have to go to the airport you could be the first or the last stop which doesn't take long but I give myself a total of 3 hours
Yup what linda said 2 hours is a safe bet
He probably want at least a two-hour window at least just to be on the safe side
