PDX (Portland, OR)
I wrote to PDX (among other places) registering my distaste for the new policies, and this was part of the reply I received from Jean Pratt, Customer Communication Coordinator:
"Thank you for contacting Portland International Airport.
The airport currently does not have Advanced Imaging Technology (full body scanner technology). The TSA plans to install this technology next spring. It will be optional for all passengers. Passengers who do not wish to utilize this screening technology will receive alternative screening, including a physical pat-down."
So, PDX will be receiving imaging technology in the spring.
