I don't think anyone has a problem with banning nuts on planes, myself included.
The problem is where does it end. I totally realise that other allergies are not airborne or whatever, and therefore are less risky than nuts, but I'm afraid a whole industry has grown up around those who are allergic to this and that. I say that with the utmost sympathy for sufferers, but honestly, this thread is nearly 1,000 posts long and still no one has provided any proof that nuts on a plane will cause devastating injury or death.
If anyone has links to deaths on airplanes from nut dust recycled via the air circulation on a plane, please let us know.
And as others have pointed out, it's all very well to ban nuts on board, but who can say whether other passengers have nut residue on their hands, having eaten them pre boarding, or indeed have brought their own food on board that may be nut laden, even unknown to them.
Anyway thread will be closed at 1,000 posts, so get your comments in now folks!
