Chimbu Chuckles has hit one big nail on the head. I can only speak for myself, but EK would have to drag me by the hair to my home town to take up a basing. The thought of losing 40 percent of my pay in tax makes me reach for the Bar Fridge.
Another problem the airline has, is that they can't really up the offer greatly for DEC's. They would then be forced to match it in some way or form for all of us already here.
