I was just on the CS from SJC to OXN (a nice little weekend getaway) and I became concerned after reaching SLO that no conductor had been by to scan my eticket. I mentioned this to George (my SCA) at SLO and he told me that some crews just ask the SCA if everyone on the manifest got onboard at each stop and then have a way of entering that info into the system.
I guess that might work with the sleeper pax but maybe not so easily in coach.
I don't have an email telling me that my return leg has been canceled because I was a 'no-show' on my out-bound segment so I'm hoping that George was right.
