A newbie here who has just noticed this rather useful thread.
Where can I find out what the letters mean? I know a couple but it would be useful to see the whole list and I know they will be somewhere in the forum but haven't found them yet.
What is the loading like for
13/3/18 LHR-JNB BA57
30/3/18 JNB-LHR BA56
Many thanks in advance
