Sorry folks, I should have mentioned some of the places:
This mainly happens to me in, BRUssel, AMSterdam, Fumi, CDG, MAD, BCN....apts
And en route, over France.
From my opinion, this "
very short time freq remaining" and "
too many times swap" may involve the air safety. Don't you think so?
I also note that there is a lot of other matters to discuss about BCN & MAD radar vectoring
