This disruption causes immemse inconvenience to huge numbers of
potential passengers including thousands of commuters and especially
those trying to catch flights out of the country at Heathrow. Any
airline passengers missing his/her flight(s) then has to rebook not
only those flights (probably at considerable cost), but also to
rearrange hotel bookings and onward travel. Airline passengers can
also potentially miss important family gatherings such as weddings or
funerals.


This is why I'll be travelling up to London the day before when I fly from
Heathrow in September,
even though the flight is not until 1400. Otherwise I'd have to leave
Cardiff around 0700 to allow
enough time for the two hour suicide or signal failure delay.
