Thanks for adding info on this. Everyone I've talked to who has worked at Wal-Mart HQ has talked about how cost-conscious the entire company is. I would be really surprised if things like private jets there weren't part of a strong cost-benefit analysis.

It also enables high level manager to visit stores and come back in the same day. Or visit 3 stores in two days.

So those same managers are more inclined to go actually visit the stores they are in charge of. Imagine having to visit 5 or 6 walmarts across different small cities, doing it commercially would take a week or more.
