Even for China, where companies have struggled with race issues in their marketing previously, the latest in-flight magazine from the country’s flagship airline will likely come as a shocker.
Air China’s Wings of China carries a long feature on visiting London, with almost a third of the magazine dedicated to tourist attractions in Britain’s capital and other famous cities such as Oxford. The main article, titled “London, the city of ‘hat tricks’,” covers Brits’ apparent fondness for all kinds of hats.
Then, after a section on transport options and lifestyle and cultural activities in London, Wings of China offers some “Tips from Air China.”
“London is generally a safe place to travel, however, precautions are needed when entering areas mainly populated by Indians, Pakistanis and black people,” China’s flagship carrier advises. “We advise tourists not to go out alone at night, and females always to be accompanied by another person when traveling.”
