Interesting.
Here I am in my trusy aeromachine at 16,500 feet (VFR) west bound, flying straight and level, passing over AA proceeding to PHX at 16,000, and he is having a fit...because the airspace belongs to him (so he thinks) even tho both of us are talking to PHX approach.
Needless to say, AA was told..."sorry, but he is at the proper altitude, call us on the telephone after you land."
Really...some of the airline guys think that the sky belongs to them, but it certainly does NOT, at least here in the USA.
