Of the 58 total 763s, 45 of them are owned (subject to liens - they secure debt) and the other 13 are leased (operating leases). I'm sure the info is out there in the bankruptcy documents about which tail numbers are owned and which ones are leased, but I'm too lazy to look. Some have assumed that the youngest nine, delivered in 2002-03 to replace the TWA 763s, would be the last ones retired, but those might still have some market value today as they're lower in cycles and hours than AA's earlier 763s. There were six bought new in the mid-late 1990s for DFW/ORD-Hawai'i (so the DC-10s could be parked). The remaining 43 are all somewhat older.
