OK - I have now read on the IAG website.
So they wish to downsize a large number of routes if this really is the case. Very odd given everyone else is slowly expanding...........
There are only a handful of the 747-400 routes where the planes are less than 80% most of the time.......
As you say for the big routes to use this tiddly little thing when LHR slots are so valuable - just seems a bit wierd...
We shall only know in the fullness of time.....
