I flew EWR-ZRH in J last night.

The gray-coated BF concierge hopped around the cabin for a while. In each case where she stopped to talk to a passenger, she was asking them if they were a OP member or if she could sign them up. In the row in front of mine, the passenger said they weren't and the concierge asked if they had status on any other airlines.

In no case did she say "welcome back MR. or Mrs. bla bla" to ANYONE that she wasn't trying to sign up. I'd expect a "welcome aboard Mr. entropy, we appreciate your business, is there anything we can help you with [shower, etc]".

Is the purpose of these concierges to provide service or poach high rev travelers?
