Might hit 20 million for 2017.
The likelihood of hitting that 20 million mark is totally possible and outstanding for a small hub airport that has a very high O&D percentage. And by small hub airport, I mean it's not a hub for AA, DL, UA, etc.
I found this quote from Bill Wyatt interesting per an interview in the Portland Tribune: "In 2001, PDX handled 12 million passengers a year. Now it's up to 18 million. Oddly, while there are fewer planes taking off from PDX than 16 years ago, the planes are larger and fuller. Only nine years ago, airlines were content with planes taking off only half full, says Wyatt."
Icelandair is here to stay, Condor is here to stay, and Volaris seems to be here to stay for the foreseeable future. As long as Alaska remains the big player here, and they will, the international flights we see will only mature and grow, and new international service isn't out of the realm of possibility within reason. I'm not suggesting we'll be at YVR levels by any means, but we're going to hit 20mm either this year or next, and this once deemed sleepy little medium sized airport is now in an entirely different category...and it happened fast!
