Should Flight 123 DAL-HOU get cancelled (for whatever reason) it doesn't necessarily nor automatically mean that Flight 123 HOU-PHX, PHX-LAX, or LAX-OAK, also get cancelled, as another aircraft could be "turned" to operate the flight, say (in this case) from HOU, and all the way to OAK. In the above scenario, it would only show up as one cancelled flight, not four.
And if only one portion of the flight gets cancelled then it should be considered one cancelled flight. If all four legs get cancelled then it should be treated as four cancelled flights.
