I think "Retard" is a highly appropriate name. I was a Heathrow controller for 31 years and I can assure you that BA gets no priority despite what you might think. You simply have no idea how the system functions. You might be number x at the hold and someone departs ahead of you from an intersection but that is very common, not because of the airline but because at the time is was tactically good ATC procedure to "fill a slot". The UK ATC system is utterly fair and impartial.
You talk so much garbage I really wonder if you are a troll. If you really are a pilot then please God don't ever, EVER let me fly with you.
