Let me refine NightIP's answer a bit to your question...

The two airplanes in the news release from today are the ones that were leased to GSS (Global Supply Systems, 49% owned by Atlas Air Worldwide Holdings)...they were part of a three-airplane fleet operated by crews employed by GSS. The three airplanes flew for BAWC (British Airways World Cargo) and later IAG (International Airlines Group) -- a company formed when BA bought Iberia.

Confused?...yeah, me too!!
