By far, the cheapest and most convenient way in and out of the Portland airport is taking the red line on the MAX light rail. A dirt cheap 30minute $2 ride, wisked us from the convention center to the door of the airport. The train cars even have a decent amount of space designated for luggage and even bicycles. Obviously, the train won’t get you to the door of your hotel like a taxi will, but for $2 as opposed to around $40, I’ll gladly walk the couple of extra blocks.
