National solution
Have no conflict of interest. I do not work for BA / MAG/ HAL however I do, and have in the past, been involved with a number of large airport projects worldwide. Currently coming towards the end of one in the Middle East in fact, and maybe being posted onto another soon. So I do know about certain aspects of airport developments, within my own specialisation with respect to terminal construction. As for other posters on this thread I would surmise that some indeed may work at airports that are being discussed, but in what capacity is not always clear.
