Quoting Ferdinando (Thread starter): Who knows the new Operating Empty Weight and range of new 772LR who must be delivered to Air India?
From A.net Aircraft Data:
The 777-200LR will be the longest ranging airliner, capable of flying 17,445km (9240nm) - 18 hours flying time. It will achieve this with awesomely powerful 489kN (110,000lb) thrust GE90-110B1 turbofans, a significantly increased max takeoff weight and optional auxiliary fuel tanks in the rear cargo hold. Other changes include 2m (6.5ft) raked wingtips, new main landing gear, structural strengthening and optional overhead crew and flight attendant rest stations above the cabin.
Operating empty weight
326,000 lb (148,181 kg)
Maximum takeoff weight
766,000 lb (347,450 kg)
Max. fuel capacity
53,440 US gal (202,287 L)
First Flight, PA001 DEL-FRA-LHR-JFK; Dream- JFK-COK on a B6 787

So I am not understanding this is there a NEW OEW for the 772LR or are we talking about the OEW of the 772LR.
One mile of highway gets you one mile, one mile of runway gets you anywhere.

It is my understanding that the so-called thrust bump option for the GE90-110B1 has been chosen as an option by AI.

The 777-200LR has been through a total of 3 performance specification changes:
1. Boeing's range/payload predictions were off by several hundred nautical miles. At the end of 777-300ER flight testing, Boeing changed the specifications of the 777-300ER and 777-200LR to be what they really were, and subsequently many more airlines ordered the planes (Boeing predicted the range/payload to be a lot lower).
2. After the 3rd or 4th 777-300ER frame, Boeing made some aerodynamic and weight improvements, thus increasing the range of the 777-300ER and 777-200LR.
3. Due to the fact that the 777-200LR still could not do SYD-LHR-SYD nonstop, Boeing made some more weight improvements to the 777-200LR, starting from the 3rd frame (the Air India frame). This is what the thread starter, Ferdinando, is asking about.

There is simply NO WAY to know the OEW of a plane without specs from the OPERATOR, not the manufacturer, which is why Ferdinando is asking about the Air India ones specifically.
The OEW of an airframe includes its interior, which is operator spec.

As I understand it, Boeing was trying to trim some 12,000lbs from the "green" B-777-200LR, before the customer added equipment was installed.

Are you certain that there has been a weight reduction ? If so it has been a well kept secret. IF OF and Boeing are talking again about the 777 as has been alluded to in another thread then it is reasonable to surmise that something is being planned in this respect but I have not seen any specifics anywhere.
The passenger ready weight of a type for a particular airline seems to be one of the most closely guarded secrets in the business and appears to be privileged information limited to a limited number of individuals within the airline.
