I'll stir the pot ....
As a shareholder I would not be impressed to find members of a firm's leadership team sitting on their @rses in a lounge awaiting boarding. I would much rather they were getting from A to B promptly, privately, securely, discreetly. Going about the business of generating me a dividend or capital growth, not waiting for someone else's timetable to apply.
Why would I object to the nation's 'CEO', 'CFO', 'COO' et al traveling similarly? It's a poor use of their time to sit in a lounge or meaninglessly fill another 3 hours before their flight to wherever is due to depart. It astounds me that so may of us have such a big chip on the shoulder about this.
