Walk out of the terminal onto the top "departures level" (if you have arrived on an International flight this will mean taking either the stairs or the lift up to level 1, which is the departures or domestic arrivals level)

Walk across the middle of the first lane which is for black taxis and buses only, then cross over the second lane.

In the middle of the far pavement on the very top level you will see some stairs and a ramp for trolleys. Walk down the stairs or ramp and turn right continuing until you reach the two ‘radio taxi’ bays (just before the ramp that leads to the exit and the entrance to car park 1A)
You should now be able to see the level 4 lifts to car park 1
Your car should be within two-three cars space of this area, though it is possible that your driver may be moved on by traffic control so please phone the office if you cannot see your driver.
