Two passengers have left their fellow travellers reaching for the vomit bag after they were involved in a "dirty" act on a plane.
A bizarre photo was taken showing the two women on an economy flight stretching their legs by putting their bare feet up on the seats in front of them.
Their feet were seen raised in the air, with other passengers looking on in disgust.
The photo has since been shared on the Instagram account Passenger Shaming where it now has more than 500 comments and thousands of likes.
Some branded the mystery women "dirty", "nasty" and wondering if they were in the middle of an "in-flight gynaecological exam".
