Flying United direct from EWR to TLV. Looks like UA84 (departing 445pm EST) has 2-2-2 (old Polaris) while UA85 (departing 1015pm EST) has 1-2-1 (new Polaris) configuration. Is this because UA85 is 777-300ER whereas UA84 is 777-200? I assume it's possible my information is wrong, but thanks for any input in advance.
