As a concerned passenger I asked the pilot today what information she had about fumes in the aircraft. She (pretty as well) kindly told me to look at the pilot union website and gave me the internet address.
For those wanting more information, the pilots have some good informative stuff. I have pasted the internet address below as it took me a while to find it. Just click on the link.
