Planes from British Airways, Virgin and Quantas are all sporting moustaches this month, in support of 'Movember' - where men grow a moustache for a month to help raise awareness of prostate and testicular cancer.
British Airways have released images of one of their jets, decorated with a trim, black moustache - alongside crew member Kyle Patchett, who is also supporting a neatly-trimmed 'mo'.
Unsurprisingly, Virgin has painted a full moustache and beard on one of its jets - perhaps in honour of founder Richard Branson.
And Australia's Wallabies rugby team have posed for pictures next to a Quantas jet, which has also been decorated with a generous 'tache.
According to the UK Movember website, more than 344,000 UK men have registered to grow a moustache in November, and have so far raised £7,612,936 as a result.
Worldwide, more than a million men have signed up, raising a total of £31,714,736 to date.
Men who take part in the campaign start the month with a clean shaven face and for the entire month they must then grow and groom a moustache.
Women can show their support by becoming a Mo Sista - essentially a woman who loves a Mo, and is dedicated to supporting the man in her life in their moustache-growing journey.
