I have been plagued with the same question, Jubilee_777! I came across an internet website which showed all of the aircraft orders airlines around the world have made, and I came across an Air Canada order for 5 A330-343X. I posted some questions here regarding this "X" anomoly and it seems no one knew exactly what it meant... I wasn't the only one who was dumbfounded.
In the past, I remember reading somewhere that Airbus was planning an extended range or increased gross weight/performance version for their A330-300s, and this is what I thought the "X" stood for. However, up to this day, I am not quite sure whether Airbus has developed these aircraft variations yet. I sent an email to the person operating the website asking him if he knew what the "X" represents, with no reply. Therefore, you are not alone with this "X" enquiry.
P.S. The only evidence which may lead to increased performance/range is that Air Canada has ordered these A330s with new, more powerful (by endurance) Rolls Royce Trent 700 series engines.

Atleast not according to the Boeing web site. The whole 777ER thing is very similar, I think, to what Eastern did with the DC-8s when they were first delivered. Origionally Douglas was to produce DC-8As and DC-8Bs. The As were later the -10 models designed for domestic US service. The Bs were the heavier weight overseas models, later called the DC-8-20. When Eastern took their first DC-8s they called them DC-8A and DC-8B in a similar and familiar fashion to the DC-7A, DC-7B, etc. Delta and a few other airlines protested this. They were origionally allowed to do this because origionally the DC-8s were the A & B model. However, under continued pressure from Delta, Eastern had to change back to the -10, -20 designation.
Now, as for the 777IGW, according to Boeing it is the IGW. There is no ER 777s (atleast, not yet). However, for years people became familiar with the 767-200ER, -300ER and now the -400ER so the term ER sticks out in people's minds more than IGW, besides, it sounds better!

The official word from boeing is that the IGW stands for increased gross weight which is what they do for any extension of range. And ER just came along with different designers calling the IGW an ER. And it has stuck with some planes but the 777 has always had IGW and always will.

Yes, it really is all very confusing. I agree that the "ER"suffix should be used on Boeing long range aircraft. Air France, I believe, was the first to use the -ER title on the fuselage of its new 777s. An ER aircraft is, by definition, an increased gross weight aircraft - i..e greater range requires more fuel, which requires a higher gross weight.
Like Trent, I too am baffled by the use of the "X" after the A340-300, for example in Aviation Letter (ALxxx etc.). I don't think it should be there and SIA calls its aircraft -300Es. The JP airline fleets doesn't use any suffix - E or otherwise.
Just to confuse matters even more, the numbers at the end are not always consistent. For example, CX, KU and SQ are among the airlines which operate 340-313s, yet the SQ/CX aircraft have an MTOW of 275, but KU (AND Virgin -313s) has a limit of 257t. AF/LH have a 271t limit. Everyone suitably confused?

Boeing officially changed the IGW name into ER for the 777.
When did they do that? I never saw anything in their employee news letter about it. Unless they changed the designation before the 777 project was finalized. I have been getting the news letters from a friend ever since the start of the 777 project a few years ago and haven't seen anything about this. And why does the web site still say IGW not ER?

I think that if Boeing builds the B772X it will be called something else not the B772ER because from what i understand in the begining there was the B777-200A Market and the B777-200B Market then the B Market turned into the IGW and now the IGW turned into the ER as every (or almost every) Boeing plane does.
That's the way i understand it, it's not written in stone.
I hope this make sense.

No,no,no. I was refering to that in the Boeing Press release they called the existing plane by the 777-200ER. If your doubt me, look at the Boeing press realese for " Boeing selects GE for Future 777 development."

This news release is from the Boeing site:
SEATTLE, July 6, 1999 - The Boeing Company said today it has reached an agreement with General Electric for the development of a 115,000-pound-thrust engine to power longer-range 777 airplanes...The 777-200X would be the longest-range commercial airplane ever designed. It would fly 10,100 statute miles, approximately 1,200 miles farther than today's 777-200ER (the world's longest-range, in-service airplane), opening long-range, transpacific non-stop service. The same size as the 777-200, it would carry approximately 300 passengers in a three-class configuration.
This is another one:
LE BOURGET, France, June 18, 1999 - The Boeing Company today confirmed Singapore Airlines' (SIA) choice of the 777-200ER (extended range) - the world's longest-range jetliner - to serve ultra long-range routes between Singapore and European destinations.

Boeing initially used IGW for the Boeing 777-200 (IGW) when the aircraft was first launched. Some aircraft were subsequently delivered as Boeing 777-200IGW aircraft. After a couple of years, this suffix was changed to ER as standard...hence aircraft from then on were delivered as Boeing 777-200ER. Example, the first couple of 777s delivered to Malaysia Airlines were called Boeing 777-2H6 IGW but the rest are called Boeing 777-2H6 ER - although there isn't any difference between them...just nice to know that the IGW aircraft were the original ERs.
