eyeinthesky,
Yes, additional levels available due to RVSM, yes still problems with the shiney new equipment on the ground...and all this is wasted because even IF the new shiny ground equipment worked as designed, there are still not enough controllers available, trained and on duty to make all that much difference with delays.
Simple question, have delays increased or decreased over the last two years or so?
If the delays have increased as reported here by others, why?
Could it be that those who are actually responsible for ATC planning in the UK/Europe are asleep at the switch?
