I had the afternoon off so I had a look at Portland IAP. Between the showers there were some nice shots possible:
Alaska Airlines flies with 3 types from Portland
Air Canada Express
Bizz jet
First highlight of the day for me
Southwest Airlines is frequently seen
Fedex has a hub with small aircraft...
...and very large ones
Delta
Second highlight for me
United
And when rain and sunshine take turns you have a chance to see rainbows
