Pilot asks FA's to "check in"
Flew SFO-RDU over the weekend, and twice the pilot announced over the PA "FA's please check-in." I've never heard that before in all my years on UA. I'm curious why he would have done it, and what it could have meant. I assumed pilots simply call the galleys "ding!" If there had been some comm problem between cockpit and galley, he wouldn't have asked them to check in (they responded by phone, not by knocking/entering the cockpit). And in this day and age, a comm problem between cockpit and galley seems like good reason to go mx.
