How about this nugget they slid in there. A BRAND NEW paragraph as it relates to middle seat pay:

5-C-1-g-(1) Notwithstanding section 5-C-3, a pilot may be re-seated out of an Economy Plus middle seat into an Economy Plus aisle or window seat if such seat is made or becomes available (due to any reason) prior to Departure.

So the gate agent can tap you on the shoulder just prior to door close and give you a misconnect's window seat. I'm not sure if this was allowed before (it's never happened to me like that), but there's a reason the company added this language....and it will likely stay in our contract for a looong time.
