Even sooner than that. At least some of the slots revert back to Alaska if the perimeter restrictions are listed, even before the least term is up.

There is also a caveat that lets Alaska Airlines reclaim some of the slots sooner than 10 years out if the perimeter rule adjusts.
No mention of how many "some" is.
