You hold for fog,
etc. You burn off your Alternate Fuel in the hold (as per
LEM's example). The fog lifts. The aircraft in front has a problem and blocks the runway.
If
LEM's scenario is acceptable practice with
any operator, (
quid's post noted), I am sure many of us would like to be enlightened before we book our next holiday/vacation flight.
Additionally, anyone who has not experienced the exotic experience of realising that the
Altn Fuel on his computer plan is somewhat optimistic has not truly experienced the "thrill of flight"
