Folks, hub-spoke, multi-hops, Florida hub, whatever - none of it matters when a simple 30 minute flight between Los Angeles and San Jose are being cancelled too[1]. Perhaps this LAX -> SJC flight happens to pass through Florida too? Come on... the crews flying these regional routes are the same crews that do it all day every day. Why are these flights impacted too? [1] https://flightaware.com/live/fleet/SWA/cancelled https://flightaware.com/live/fleet/SWA/cancelled

> Perhaps this LAX -> SJC flight happens to pass through Florida too? The route, no. The aircraft, very possibly. An aircraft that flew from MIA to LAX last night might be the one intended to fly the LAX to SJC flight today. The flight crew aren't glued to the plane.

I mean... which specific LAX -> SJC flight did you have in mind? Flight 3027[1] does LAX -> SJC, but first it does TPA (Tampa) -> STL (St Louis), and STL -> LAX. There may be some back and forth flights, but if that plane goes back to LAX right away, it's probably flight 2497 [2], which goes to BWI (Baltimore) after LAX. If that plane can't leave Florida in the morning, there goes your noon flight to SJC, and your early afternoon flight to LAX. Plus, the plane may not have made it to Baltimore and the schedule is messed up the next day too.

You really have no idea how airline scheduling works. A typical trip pairing for a cockpit crew is for 4 or 5 days going all over the country. Start in Atlanta, fly to Miami, back to Atlanta, then to Vegas, sleep there, next morning back to Atlanta, then on to Phoenix, and back to Atlanta again, on to Houston and sleep there. Etc etc for 4 days in a row. So a problem in Miami could easily cause delays and cancellations on a flight that to you looks totally unrelated. The only reason you have less impact in a traditional hub and spoke system is that there are extra aircraft and reserve crews in the hubs (some are at the airport, some at home at a few hours notice) and every other flight passes through the hub. So if the Atlanta to Miami and back thing goes really wrong, another crew and aircraft will fly the Atlanta to Vegas flight and sometimes the rest of the trip. Doesn't happen for a simple delay, but if the delay pushes the crew over their duty time limits on the outbound flight for example the return to hub would be cancelled and a reserve crew would pick up the next flights starting from the hub. The timed-out crew would go to be hotel and fly back as a passenger with the next days flight.
