Sick???
Sick of what, Being in economy class, Sick of get what you pay for?
To be honest I don't have much belief in these claims of pax getting sick,
It's the usual 'media' hype that generates all these claims, Yes they may be the odd and that's a very odd flight that does get the odd smell of the Aircraft, But hey it's a working machine and machines do smell.
As an example in all the years of BY/TOM I have only ever heard of one such incident of pax feeling poorly, A flight inbound to BHX about 11 years ago on a 757.
I don't disagree that pax can't get poorly/sick, But when you weigh up all the potential compo cliams I'm not surprised.
If there is a chance of fumes/smell in the Aircraft it's usually in the cockpit.
I don't implaud to be rude, I just think it's all in the mind
Regards.
