What a Proper Meet & Greet Actually Looks Like at Arlanda
"Meet and greet" gets used loosely by a lot of operators. Here's what it should actually mean when you're the one walking off the plane.

A lot of transfer services advertise "meet and greet" and mean something closer to "we'll be in the car park." Here's what it should actually involve.
The chauffeur is inside the terminal, not outside. A real meet & greet means your driver is waiting past the arrivals gate, inside the terminal building, holding a name board — not circling the drop-off zone or waiting at a curb you have to find yourself.
Your flight is being tracked before you land. The chauffeur should already know your flight has landed, adjusted for any delay, before you've cleared passport control. You shouldn't need to call anyone to say you've arrived.
There's a buffer built into the timing. Between landing, passport control, and baggage claim, arrival-to-curb time varies a lot depending on the flight and the day. A properly run meet & greet accounts for that variability rather than expecting you to appear at gate exactly N minutes after landing.
Help with luggage is standard, not an upsell. Once you're met, the chauffeur should handle bags to the vehicle as a matter of course — not a separately offered extra.
If a "meet and greet" quote doesn't clearly include all four of these, ask directly. It's a fair question, and a reputable operator will answer it without hesitation.
