Portland Int'l is by far one of the most pleasant of "smaller" major airports. Even though it's not a major hub to any one airline, there is considerable service by Delta, United, Alaska, and southeast. You can fly to almost any major airport in the country non stop from Portland. The Terminal is relatively small, very easy to navigate, yet offers a wide variety of food and shopping choices, both inside and outside of security. Best of all, there is no tax, and the airport forbids unfair marking up of goods bought inside the airport. That is, if you buy a bottle of wine or a book, you'll pay the same price as you would anywhere else. Wall to wall carpeting and plenty of windows make it a cheerful and soothing environment. If your travels take you through Portland, you should enjoy yourself!
