If frequent travelling and entertaining is your ideal job, I suggest to take up a global or regional project role in a top MNC in FMCG, property or O&G industry.

Their travel benefits and entertainment budget is much bigger than your typical management consultancy anyway, but only a minority can live this kind of lifestyle long term - it gets boring & tiring after a while.

When I was with Chevron few years ago, chalked up enough points to get Solitaire membership and Hyatt Diamond within a year. At first I thought not bad can change free flights and stays when I want to go holiday on my own, end up so sick of travelling I stayed in Singapore for all my leave.
