Or, at times tacking on something that seems bizarre like LHR-BRU with a handful of pax on board. This has something to do with no losing precious LHR slots (which are taken away if they go unused for a period of time).
In terms of HKG onward to SIN/BKK. The flights continue but the aircraft no longer do, with UA using a smaller a/c for that last portion of the flight - a change that the FFs did not like for obvious reasons.
