Ask em to let you know once they pass immigration (if international arrival) and are waiting for luggage.

If you live 30-45min away, once they pass immigration, you’ll arrive maybe 5-10mins after they walk out. So 5-10min wait for them is nothing. They are not “rushed” out of their spots. Meanwhile you’ll get yelled at if you don’t move out of the spot for 3mins.

As others said, pick em up at DEPARTURE levels, not arrivals. DO NOT go level 1 for B. If you end up couple mins early (i.e. they are walking out with baggage but not outside yet, make another loop around the airport and go back).

Also i always ask to wait for me either at the end or at the beginning of that sidewalk. Usually less traffic and you can GTFO without 174017491 cars blocking you and honking at you.
