Thanks, Jasper. I contacted Royal Airport Concierge and here is the reply I received.

For your arrival, our greeter will be at the arrival Gate with a name sign. Passengers are expedited through immigration/customs. Greeter will retrieve & collect luggage for the passengers and then escort to their pre-arranged car waiting for them curbside. The rate for this service is 450USD up to 3 passengers.

To proceed please provide:
⦁ Passenger’s full names
⦁ Flight information and date of travel
⦁ Mobile number
⦁ Transportation Details /Driver Details

For cancellations we require 48 hours prior to the service. Under 48 hours, cancelled booking/s will be considered late cancellation and full charges will apply.

Unfortunately, that is more than we are willing to spend at this time, but I thought I’d share this with the forum.
