Depends on the arrival, but if they're doing the typical runway 7L arrival coming in over Turnagain Arm, I like to sit on the right side. The left is better for a city view on the runway 14 arrival (although the right gives you a beautiful view of the Alaska Range mountains), but unless there are strong winds out of the south, they usually arrive on runway 7L and depart on 32 (14 in the opposite direction).

Oh, and no p.s. service up here! (Though I did fly on a subbed p.s. once from LAX to SEA, I think...too bad it didn't continue to ANC...)
