Exactly.
It works for me!
per UAs website,( and a letter in the mail),holders of the CONTINENTAL PRESIDENTIAL PLUS will continue enjoy "priority boarding & will get group 4 (general starts at 6).
That's correct.
that is what is published...but there are glitches.
however on my last flight i (presidential plus holder) was given group 6.
the GA claimed not to know anything about presidential plus..
