We were just informed of an aircraft change for my flight home from Taipei tomorrow on UA872. We now have N2140U. This note is to confirm that the info on the "Polaris Update" page is correct - my new seat map is showing a Premium Plus section.
And more important (if you happen to be me!), they reassigned my seat to 21B, i.e. Premium Plus aisle seat at no extra cost. I'm starting to like sittin' in the Big Chair.
