leaving out of terminal C at 7:20 AM at IAH. how early should i get there to beat the traffic?

hey guys! i’ve been seeing a lot of talk about IAH’s terminal closure, and wanted some suggestions on what time i should arrive to the airport for my 7:20 AM flight to avoid the long line of cars. i was hoping someone else has had a flight time similar to mine and could help me out. thanks in advance!
