Expect the Norm with New Roster System
Guys,
Heads up! This is what the new rostering system was brought in to do, so get used to it systemwide from now on in every city with multiple daily flights.
Unlike the present Ad-opt system, which builds the rosters from pre-built pairings, The new roster system can optimize the pairings and the rosters simultaneously, thus opening up plenty of possibilities for shorter layovers in FRA, CDG, SIN, BKK, HKG, LHR, MAN etc.
Don't say you have not been warned.
