I just flew out of PDX on Tuesday morning, and I got there about 90 minutes before my flight and had time to check my bags, go through security, drag a bunch of carryons and a 4 year old through the airport, and I made it to my gate with easily 20 minutes to spare before boarding. This was with Tuesday morning Thanksgiving crowds.
When we flew to PDX a week before, we got stuck in traffic and made it to the airport 40 minutes before our flight, and checked bags and got to the gate with time to spare.
