Very interesting thread indeed. What triggered my reply was unexpected appearance of TRA in negative connotation. I was very surprised. Always pleasent, helpful and cooperative. Never ever had I problems with them. Usually, it is UK airliners that are pain in the a.. To be precise, most of the times BAW and BAL. Twice I was asked about my radar separation minimum, so meny times they were complaining and asking for reason, even if you ask them to increase or reduce their speed by 0.01M. Not to mention level change! Blasphemy! Almost like JAT, Serbia's national carrier, who is the worst one, undoubtedly.
