This is a fascinating look at what Alaska Airlines is planning to do in order to route more connections through PDX. Also includes some discussion up the page about how Alaska is making Hawaiian's network more efficient.

Portland Gets Banked
Over on the Alaska side of the house, the airline has decided to turn Portland into a real banked hub instead of the modified rolling-style hub. The latter is better for utilization of airport resources, but the former is generally far better from a commercial perspective. Alaska has relied on Seattle as its big hub, but now it wants Portland to step up and take more connections.
Hereʻs a look at a chart we did for this weekʻs Cranky Network Weekly.

As you can see, there are now five clear banks of flying and very little in between. To make this work, Alaska needs more gates and quite likely more employees. I assume that this is all now possible since the airport’s big renovation project is done. Alaska just had to decide it was worth the investment.
