"Oops ... She's going back to the shop!" a company social media staffer joked on Twitter.
Cathay Pacific however, did not clarify whether or not the images are real or who are responsible for the supposed blunder.
Cathay Pacific recently gave one of its planes a brand new paint job, somehow making a slight spelling error in the process.
Travellers had spotted the mistake at Hong Kong International Airport and contacted the airline, which said it was a genuine mistake.

The airline claimed it was an honest mistake, but others were left wondering how such a huge error could slip by unchecked.
"I guess the "F" isn't working on someone's keyboard..." one person wrote, while another said, "Leave it as-is and put a red squiggle underneath".
While the company claimed it was an honest mistake, an engineer for aircraft management firm Haeco told the South China Morning Post he suspected the company may have intentionally made the mistake to get a little publicity, since it would be an extremely hard thing to happen by accident and it would cost hundreds of thousands of dollars to fix.
A spokesperson for Cathay Pacific told CNN Travel: "We did not intend to make it a big fuss in the first place, but photos went viral within the aviation enthusiastic groups, so we just shared the hilarious moment with everyone".
