Security checkpoint times can vary widely in the States. As can the transportation to get to the airport (traffic, public transport, parking, shuttle). And don't get me started on kids and family members who don't travel often.

Three hours is totally unnecessary but the asymmetric risk of missing a flight vs posting up with a beer and a gameboy tilts things toward an earlier arrival.

It's refreshing to travel from a regional airport though.
