I leave my house for LAS flights only 1 hour prior to departure. It is 10 minutes to drive to the airport, 5 minutes to get to the security line, 5-10 minutes to get thorugh the elite line and then 5 more minutes to ride the shuttle to the D gates. Total time 30 minutes...
But the most important thing in all of this is the fact that I do OLCI. Moral of the story? Do OLCI.
