Assuming people from the greater Portland area fly into and out of PDX, here’s some places headquartered in the area that could be affected by protests at the airport:

• Intel, which must have quite a bit of airline traffic at PDX invests heavily in Israel.
• Adidas, which must have quite a bit of airline traffic at PDX uses an Israeli Manufacturer.
• Wells Fargo (and BoA), which must have quite a bit of airline traffic at PDX has given loans to Israeli weapons manufacturers.
• Boeing, which must have quite a bit of airline traffic at PDX provides weapons to Israel.
• HP, which must have quite a bit of airline traffic at PDX runs the biometric ID system that Israel uses to restrict Palestinian movement as well as other systems for the IDF.
• Siemens, which must have quite a bit of airline traffic at PDX is involved in the building of Israeli infrastructure.

So while, yes, the protests definitely inconvenienced random citizens, it has a pretty good chance of also affecting these companies as well.
