UA would do an equipment swap on LAX
flights when things would get backed up at its SFO
hub - if 3 or 4 departures on this busy route would be cancelled or delayed, or many pax had to be cleared out due to irregular hub operations, UA
would pull out a 744 to take 300-400 pax down from SFO
- or vice versa. I dont think that a 744 has been regularly scheduled for this short flight.
You ask an interesting question - there is far less domestic widebody service within the US than, say, 20 years ago, with airlines more focused on hubs and frequency. I can remember when intra-state routes like DFW
, even SPO-SEA
were served with wide-body aircraft; at the moment, I cant think of another intra-state widebody flite.
