This is from the article:

As for the new $5 fare on Blue Line trips beginning at O'Hare, customers who use monthly passes, Chicago Cards set up as monthly passes, or one-, three- and seven-day passes will be exempt from the fare hike. Reduced-fare riders also will not pay more, officials said.

So it sounds like people with true monthy passes won't pay a the higher fare, but people like me who have a pay-as-you go Chicago Card will. Most ORD workers probably use the monthly pass option, but I'm sure many of the airline employees I see on the train who are only in town a few times a month probably don't.
