Whilst I believe a boycott won't work for practical reasons i.e company cars = company fuel allowances, it nonetheless focusses the 'little guy' on something. The fuel protests of 2001 only achieved a partial success due to the lorry drivers picketing oil installations. Since then fuel has tripled and we stand by, apparently helpless. Don't know about you, but I was lead to believe, the UK government takes around 85% in duties and tax so diesel at 120/lt is a pound for Golden Brown.
Why are Emirates/Etihad/Qatar buying aircraft like gifts at a pound shop? There won't be a emirati green tax. Their access to heavy oil (processed to make kerosene) ensures that derivatives are about 10p a Gallon - retail !! Level playing field - not !!
If BA decide to do this, we'll just be flying in different colour aircraft in the future.
