This is really nothing new.

In my over 25 years of UA flying, whether you call it Connosuier Class, United Businees, United First, BusinessFirst, Global First or Polaris, FA storing their bags in premium cabins are standard practice at UA.

Simply renaming or rebranding to “Polaris” is not going change the behavior or practice.

FA are there for primarily for our safety not for providing OH space for passengers.
