Whilst I tend to agree with the BA point of view - I do not agree with the situation wrt to Chapter 11 and the US seemingly wanting Open Skies on their terms.
Yes. BA had subsidies in the early 80s but the playing field has changed somewhat.
We (the UK) seem to abide by the EU rules on subsidies, wheras some of the European carriers clearly do not - Alitalia being a prime example, Air France is highly suspect too.
I don't really see how we can criticise the US in this so called 'one Europe' when we as Europe do not have our own house in order.
The US have always been outstanding in protecting their own markets be it by having different mobile 'phone frequency ranges, to Chapter 11 rules.
If we specifically talk about BA then there is the whole issue of access to LHR and Grandfather rights - now how fair is that ?
