Eric Tellman was the Spirit FO on the trip mentioned in the article. He took the lead on Industry awareness of this all too common, but often swept under the rug problem. He was the Environmental Committee Chairman for Spirit and I believe has recently taken on a similar role with ALPA National.
Spirit took steps to resolve the issue, but Fume Events still seem to be occurring. They changed oils, started using upgraded cabin air filters and implemented Fume Event procedures guidelines.
For awhile JetBlue was changing engines after every event, but eventually ran out of spares. (Told to me by a JetBlue Pilot, so not first hand knowledge.)
