WN was never in T2 or T3. They went straight from T1 to T4, and the wrecking ball was poised to take down T1 the day after they moved.

HP's original hub was in T3 with two separate south concourses - one was made out of wood! Two of the gates were designated for parking the B742's. HP moved from T3 to T4 on the same day that WN did.
