Another related battle in Chicago
Keep your eyes on a lawsuit on a similar matter in Chicago, Illinois. It is by twenty passengers on an XL Airways Boeing 767 back in 2007, when a fume event at altitude seemingly liberated VOCs, with nasty results.
Boeing and others tried to get the case thrown out and back to the UK, but lost in a headline decision earlier this year in May. The case now proceeds in Chicago to damages. Watch this space.
The important issue for all here is that a single fume event is much less complex to prove in law, than prolonged exposure by flight or cabin crew to conditions, say in a 146 or 757. Something lawyers cause "causation" is the heart of the matter for these types of case.
As a matter of decency and simply doing the right thing, there has been a deliberate ducking of this issue by the industry for far too long. David Learmount and others are correct to call it the dirty little secret of the aviation industry, ably abetted by insurance companies and others who are keen to protect their capital from claims.
There will be "an Erin Brokovic" for toxic cabin air, it is just a matter of time.
