I notice the early LHR-SFO is moving from its usual 1030 slot to 1125 as part of the revised Summer Schedule.

I always take the later flight anyhow (1350 dep) because it's an easier run into LHR and there are no queues at SFO Immigration (normally).

I wonder if BA consider things like this when scheduling. For instance, I never take VS19 to SFO becasue it was always due in just after the BA and who wants to find themselves behind 350-500 people in the Immigration queue. Now I might consider it as the VS lands first and for sure BA 285 is completely off the menu.
