Terminal 4 is physically separated from Terminals 2, 3 and 5, sitting on the south side of the airport, on the other side of the runways from the Central Terminal Area.
A different approach road
Because of that separation, Terminal 4 is reached via its own dedicated approach road on the southern side of the airport, rather than the route used for the other terminals. This adds a little extra distance and time compared with a Terminal 2, 3 or 5 drop-off — worth factoring in when you're timing your journey.
Set-down area
Terminal 4 has its own set-down area directly outside the building, a short walk from check-in.
Confirm before you travel
Terminal 4 tends to be quieter than the larger terminals, but it's still worth confirming your exact terminal on your boarding pass, since assignments can change between bookings.
Booking your transfer
Let us know it's Terminal 4 when you book — since it's on a separate approach road, your driver will plan the route accordingly rather than defaulting to the Central Terminal Area.
