- For me, it's always been a pleasure to fly Southwest Airlines PDX Terminal out of the Southwest Airlines PDX Terminal. The terminal is modern, spotless, and simple to use. I adore how easy and quick check-in and boarding are made by the Southwest staff. I never feel hurried or congested while waiting for my flight because there are plenty of nice food options and enough of seating. One big plus is that my flights have always left on time. I always look forward to flying Southwest from PDX because, all in all, this terminal makes traveling enjoyable.
