I notice that a number of airlines lease aircraft from banks. AirTran, for example, leases its entire 717 fleet from Wells Fargo Bank Northwest, according to Bill Harms' census, but company literature says the 717s are financed through Boeing Capital Services.
How do leases of this nature work? Are they leases signed for a term (as in a "traditional" lease from ILFC, AWAS, etc.), or are they some sort of lease-financing arrangement?
Does the aircraft return to the lessor at the termination of the lease with institutions like WFBN, or is the contract renewed indefinitely?
