Worst aspect is that if we do arrive early we have been told to expect delays in disembarking pax and baggage removal, as the contracts are all based around ontime performance! Same presumably applies if late - even more delays. It is very frustrating to pull on stand 10 mins early and then wait 10 mins + to disembark pax and offload bags - yet it happens frequently (more and more frequently as post above in multi colours confirms!). So whilst performance is improving (I have seen that) getting there early makes it feel worse for our customers as they then wait an eternity to leave the aircraft and get their bags. Bring back BACON - at least they were flexible!
