I'm Flying ORD to MUC on Saturday, UA flight 952. This is a paid J ticket (Polaris Business) on a 777-222, on an old three class plane.

At check in this morning, it allowed me to select seats in the old United First/Global First section (where there's only 8 seats instead of the normal 16). Is this normal or am I going to be kicked out of these seats when we go to board tomorrow evening? The label on the phone called it Polaris Business so I assume it's okay but I'll switch back to our old seats if there's a chance we'll be kicked out of that section by the GA. 3

Has anyone else come across this yet?
