Historically, a trip like JFK-SFO-EWR would have earned 5,151 BIS (2,586 on JFK to SFO and 2,565 on SFO to EWR). However, having flown both routes within the last few days, UA has updated my lifetime miles at +5,153. Either one or both routes may have had some recent changes.

For the record, prior to the September trip, I haven't traveled between JFK and SFO since around mid-May, and between EWR to SFO since late January. Will be back on one of these routes later this month for additional data points.
SFO-EWR is still 2565, I believe. Do I understand correctly that in mid-May your JFK/SFO flight credited 2586 BIS? I have not flown that route for a long time, since before the merger.

I have started trying to take a screenshot of my BIS counter after every segment on a new route for myself, since unfortunately they don't publish their itemized tallies in any way after they killed PQM.
