Lets see how far this will go and how successful she will be in her bid to wring some money from Boeing. She is going to have a tough case proving that one occurrence of a "smokey mist" caused her problems, but that her fellow cabin attendants suffered no ill health after the exposure.
These claims have been numerous, but I can not recall that anyone has successfully sued an airline - might be wrong but I doubt it!
I have been flying for much longer than she has, and I do not suffer from these problems. Maybe I sit in a "cleaner" part of the aircraft!
Life is a terminal disease - who can I sue?
