I have encountered more delays than I care to recall with the aircraft
being unable to get off its gate on time or up in the air on time or the
clods at Heathrow being unable to unload a plane in anything less an
hour - even when its the first one down in the morning so there's excuse
that "they're busy emptying another aircraft".

This is one reason I prefer flying on low-costs for short-haul - steps
at both ends, and a significant incentive to turn things around
quickly. (Another is that easyJet's booking engine *just works*).

Even then, though, arrival time is not predictable within a 10-20
minute window once you get later in the day.
