Yet another missing miles episode for me on UA metal fights. Latest was EWR to SFO. In fact, of my last 6 RTs, all 6 have had one segment go missing for 10 business days until I submitted a request. Only thing that is in common with them is all involved an SDC, and all involved just one of 2 segments failing to post. Other segment posts in normal 2-3 days.

There MUST be a new IT issue causing this. Never happened in years for me, and now it is almost every trip.
