If any one starts to talk about load factors and revenue models I will scream.I did see a TV interview many years ago where Buffett told that he flew economy, I am not so sure that he still does this. If Buffett flew my airline, I would comp him. PR like that money can not buy. Alison Redford is a politician, it would look bad for her to be comped. As I said before, upgrading VIPs and frequent flyers are good for the airline as it cost the airline nothing because the upgrade is only available if there is an empty seat in business or first class and it frees up a seat in economy for a paying customer. So really it makes for happy customers and the airline is out a few drinks.
