(USA Today) -- US Airways has apologized after a pornographic image was sent out from its Twitter account.

The image was tweeted at least once to response a customer who complained to US Airways in a tweet saying: "You ruined my spring break, I want some free stuff."

The exact circumstances around the incident weren't immediately clear, but the airline apologized for the incident.

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

Because of the nature of the photo -- and the commentary surrounding it on Twitter -- we are providing no further links or photos on the subject.
