United Airlines Airbus A350-1000 configuration released

In a recent twitter post, airplane seat manufacturer i.e. Zodiac BE Aerospace officially revealed the configuration of United Airlines Airbus A350-1000 configuration which is as follows:

Total - 337 seats split across 3 cabin classes i.e. 60 business class + 91 Premium Economy + 186 economy class

These planes are expected to initially replace UA's aging B744s which accommodate 374 passengers in a 4 class layout. It is not known as yet which routes will be operated by this aircraft initially but to the naked eye, it is best to be used on the long haul trans-pacific flights as the cost savings versus a B744 are significant.
