Yes, American is getting rid of the DC-10 before getting rid of the MD-11. It's normal, the DC-10 is much older. Like I said in one of my recent post about the MD-11 at American, the DC-10 will be gone next year (I suppose, oh well I'm pretty sure about that), the MD-11 will be around for an additional two years.
What is 2000? It's the end of the DC-10 at American.
