As someone has said, the ZZ* aircraft have a reduced range (being 'A' market models) and their engines are (iirc) GE90-76s not -85s.
I think the 77Ws also have a reduced range from normal - a BA engineer told me (when I was sitting in the cockpit of G-STBA before it was delivered from CWL...
) that they had specified slightly de-rated GE90s for the 77Ws to prolong engine life and because the BA route network doesn't need the full range of the 77W. That would assume that there was a lower MTOW available on these frames and therefore a reduced maximum range.

Thank you Prospero. Your work on this is much appreciated.
I have referred to the AVOD Guide on the Dashboard but I'm still rather confused by the difference between Upgraded Tes, THALES and GMIS. Am I right in thinking GMIS is the poorest of the 3 (especially if in F on a G-ZZZ*) and that Upgraded Tes is the norm on 747 in CW with THALES being the cat's cuticles?

The 772s with Rockwell Collins (Upgraded TES) did not have NWT/NWTP fitted.

Are the 777s registered G-V*** (and RAES) 777-200IGW rather than ER? (I thought only the G-Ys were true 777-200ERs (the ones which can do MRU and HND and the like)?

The LGW 777's all have on-demand IFE. If you log into MMB, you can call up the movies being shown on your flight

Next they sold the B Market version which was also called the IGW (Increased Gross Weight) which as it says is heavier as in greater payload and greater fuel ie range. These are the VII's (and RAES).
This is where my memory is clouded it Boeing then introduced Extended Range 777's which BA bought for their next tranche, the YMM's but at some point Boeing dropped the A Market, introduced Long Range (LR) 777's of BA have none but then they (Boeing) started calling all non A Market aircraft ER's. Now Boeing only sell ER and LR but the ER's include what was once called the IGW.
IGW is the old name, now they're all called ER's.
BA's GE engined 777-200ER's do not have any crew rest facilities which means crew hours often limits which routes these aircraft can fly. All YMM's (and the 300's) have full overhead crew rest giving much greater available crew hours.
You can tell a LR as it has the extended raked wing tips and GE90x engines with the curved fan blades, both of which you'll also see on the 777-300's. Londons geographic position means there are very few routes which an ER is unsuitable.
Sorry, I only meant to answer the IGW/ER issue it kept on rabbiting on a bit too much

This looks like it's probably the right place for this question.
I've been hunting for UD seats the past few days and just noticed that the plane type is listed as 74G. The return flight is on a 744.
Anyone know what the difference might be?
