Nothing wrong with jets.... IF....you have substantial overseas operations (or your home-turf is the size of the US or Australia).
Tesco are the second biggest retailer in Eastern Europe and Turkey. They are huge in the
Far East and actually have an academy in Seoul. They have suppliers and investors all over the Globe who need to be visited and schmoozed.
If that isn't a case for corporate jets, everyone on this site might as well all pack up and look for another career.
BTW did you know they have ships too.....it's a global business, go figure...
