US Airways announced this week that it will not fire the employee who accidentally posted a pornographic tweet on Monday. 

According to CNN Money, the company said the tweet was simply an unfortunate gaffe.

The tweet in question was meant to be a response to a customer's complaint about the carrier's the service, but the post linked to an unspecified pornographic image from US Airways' account instead. Airline officials said in an official statement that the link should have taken the patron to a webpage where clients can submit their claims.

The sexual image came from a post another Twitter user sent to US Airways hours before. Officials from the carrier tagged the tweet as inappropriate, but the person in charge of the Twitter account accidentally managed to include the link to the picture in the tweet.

"It was an honest mistake and it was done while capturing the tweet and flagging it as inappropriate, our standard procedure," spokesperson for US Airway's company American Airlines Group Matt Miller told CNN.

US Airways officials said they won't penalize the social media overseer, but will spot-check the company's Twitter account to ensure that this kind of thing doesn't occur again.

The airline deleted the tweet immediately after it was posted on Monday, then released an official apology on its Twitter account.

"We apologize for an inappropriate image recently shared as a link in one of our responses," the tweet read. "We've removed the tweet and are investigating."

More than 400,000 followers saw the lewd tweet, CNN reported.
