With MHT being in the corner of their network, the situation has been that flights never continued past there, and the next segment was something they wouldn't expect anyone to take, so why waste their breath giving instructions to thru pax; I'm not sure if they do list some thru flights now.
I was on flight 1238 on Christmas Eve flying BWI-MHT. The aircraft was continuing on to MDW (different flight number), but there were probably about 10 connectors on this (not quite full) flight. The cabin crew came on the PA during the delay on the ground at BWI (waiting for connecting bags (I guess I'll give a pass for that, being the last flight of the day on that route on X-mas eve)) telling the connectors that there was no chance at all of a misconnect, as they would be on the same plane throughout.
Such situations (ala flying BWI-MHT-MDW) are probably extremely rare, but especially in irrops or holiday schedules, they're probably common enough that any employee can expect them.
