Supposed to be hats on in public, though many hats do seem to go mssing and uniform stores ( another long story) are very slow at getting replacements
...
I hate head-wear! (out-dated, pointless nonsense that I can assure you customers belonging to the 21st century don't give a damn about).
Maybe, some customer surveys seem to say otherwise and I believe following recent changes hats are back "in" at at least one other major UK airline.
Must admit being ex-Mil the hats are fine by me, especially as it hides my grey hair... and it's very a useful place for storing ID, keys, rank slides, pens et al when down route......
