It just says no Polaris not retirement and they already are in the BF two-class configuration. Obviously, the 24 remaining three-class 777s are the Polaris priority.

United also has another 13 787-10 coming 10 of which will be flying before summer and 13 more 787-9s. If those 11 'reported' 787-10s are real United would be headed for 12/38/25 (8/9/10s) for 75 787s.
