My encounters with Lineages have been few and far between. From memory, one at McCarran is the only one that I immediately can recall. There may have been another but it would have been parked somewhere probably. Seeing one taxi out at Boeing Field was, therefore, a pleasant surprise. Since it would only be taking off past me, it wasn’t going to be a great shot but still better than nothing. Then they thwarted me. Instead of crossing over to taxi to the full length, they took the intersection departure. 7,500’ is obviously plenty but still very annoying.
