Realise Avgas is taxed, but thought we were discussing airlines.On the point of a contract to get you to your destination I agree,IF the fair is good value.If an airline is going to charge me a full service fair (I think you would agree that £432 London to Moscow is that) then I expect a full service.BA charge identical fares but don't charge for drinks,guess which airline I will be using next time.(a fact which I have pointed out to BMI)
