Air China may be about to commit PR suicide. As Londoner of ethnic minority myself, this one went rather too far.

That's right, in 2016 Air China is “precautioning” travellers in its in-flight magazine to watch out for “areas mainly populated by Indians, Pakistanis and black people” when roaming London. My guess is you will not get very far as there are large settlements of the aforementioned, and many other nationalities, in pretty much every Borough of London.
Air China did later issue an apology, stating that the original advice had been mis-interpreted. Yeah…right.
