I once got to use the LHR airside inter-terminal bus
when travelling *from* Heathrow (rather than when in transit). I was
going to Lyon (on BA) and just assumed the flight left from T4, like the
Paris flights.

When I flew Lyon-LHR on BA about four years ago it arrived at T4.

Having got through security, I was puzzled to see no sign
of the flight on the departure boards and then discovered it actually
left from T1.

One of the reasons for security examining boarding cards ought to be to
stop that kind of mistake happening.
