Same airline... different paint job and country. Has happened in the past, and will happen in the future. The application form that is signed clearly indicates that all signatours on the card are responsible for charges incurred.
Another detriment is that the company can authorize charges an any and all company cards through telephone purchases, unless any restrictions are placed on said card.
Very dangerous in these hard times... beware!
Landing and ground handling fees as well as fuel can be prepaid. Hotels and ground transportation can also be prepaid thus company credit card is not a requirement in most situations.
