The advertisement depicts the derriere of air stewardesses clad in tight black and orange skirts, with the figure “50%” discounts inappropriately placed on their bottoms.

Critics dubbed the advertisement sexist and distasteful.

The advertisement was first posted on Firefly’s Facebook page on Monday, with the caption “Come grab it real fast”.

It came under criticism for its sexist tone, but the same ad was posted again yesterday with the caption “Ooopps we did it again”.

One commenter, ‪Heather Smeaton, said: “This ad is incredibly sexist and is, I think, disrespectful to women. To offer discounts, which are printed on flight attendants’ bottoms (are their ‘services’ for sale?) gives a terrible impression about how you view your female staff and women in general. I think you should come up with a new ad.”

Another also commented that “Firefly should sack their entire marketing team”.

Firefly has yet to respond to the comments.
