Travelling in Uniform
I would never have travelled by Commercial Air while in the RAF, but I have done with the Canadian Forces. I was "upgraded" to my own double seat on a packed ac and the Canadian Customs Service were actually quite civil to me when I re-entered Canada from the US.
Here in Ottawa it is very usual to see military members in uniform in public; I've even had people thank me for being in the military while I waited for a bus (public transport in Ottawa is actually reliable) what a difference to the UK!
