Portland International is one of the easier major airports in the country, which is exactly why executives lose time there. The friction is never the terminal. It is the twenty minutes between the gate and the road.
We track the flight, not the schedule. If you land forty minutes early your chauffeur is already curbside; if you sit on the tarmac for an hour, there is no waiting fee and no phone call to make. Meet-and-greet inside baggage claim, a name card, luggage handled, and a cabin already set to the temperature you asked for. The whole point is that nothing about the arrival requires a decision from you.
