TIES?...
What about ties in summer. I can understand wearing a full uniform (jacket, tie, cap etc) when one has to walk through airport terminals and is in the public eye. But to wear all this cr@p when doing regional multi sector flights and departing from briefing to the aircraft on a crewbus with the public nowhere in sight is crazy. Who you gonna impress, the Capt/FO ? Certainly not the cabin crew, engineers, flight dispatchers, refuelers, bagage handlers and cleaners!
How about the option of a open neck shirt? Especially in the warmer climates.
