No Sig....
Thanks for that. My concern was that the airlines were being promised something by NATS Management that was not true, and indeed not possible.
To find a letter from BA to NATS implying that there will be no impact suggests that either:
(1) BA haven't been told the Truth
(2) Mr. Cheese & Ham doesn't know the truth
(3) Mr Edington and Cheese & Ham have been mis-advised by their people.
My concern is that the ATCOs and ATSAs that actually provide the service would be the first to be blamed for the inevitable safety related flow delays, NATS managers having seemed to be less than honest with the airlines about the serious impact these measures WILL have.
