Most people in airline management are so sick and tired of trying to beat this thing to death that they have given up.
There is so much more that has a higher priority - rightly or wrongly - and the stealth method used by the Smiths to introduce this fiasco is aimed correctly - make little noise and those that pay the bills won't know what has hit them..
The introduction of Airspace 2000 by stealth is a disgrace, and both Smiths should be ashamed of themselves.
Have a merry christmas to you all - hopefully you will be with your families and not in an aeroplane....
