8 717's are "owned", all 8 have been encumbered under a debt facility. None of the 717's are owned outright.
78 717''s are leased. 41 of the 78 were sale/lease back transactions, the other 37 were purchased by a third party and leased to airtran. The leases expire through 2022.
Boeing could care less what happens to the 86 717's, there have been sold and the lease payments are going to someone else.
The Boeing Capital Co is the lessor.
