GRU (our last long-range trip) went to the 400 at the end of last month (I was operating the last Triple).
LUN (Lusaka) was a 777 trip a couple of years ago (only managed one).
The LGW trips aren't so good now. The ATL is being reduced from 3 crew to 2 in the New Year, the ANU always seems to be shorter these days (no full day off) and Texas/Florida are rarely long enough to be able to go and do anything.
Don't get me started about the bunks, not that we need them now!!
Edited to say: Perth, you're 'aving a larf mate!
