Adrian, thanks for all the incredible insights you give on this forum, they're truly some of the best posts I ever read.

But to rebut this particular bit, T5 can be a mess, yes. For example the 25 minutes sitting on TWY A between TWYS E and D, and then another 10 at SNAPA, all while waiting for a stand at 0625 on a Sunday was strictly un-necessary, it beggars belief that the flagship terminal at LHR can't find a stand for a 744 on a weekend.
