I'm self-employed so I'm conscious of the cost.
For the past few years travelling into Asia I've always purchased an economy class ticket but by choice travel on Singapore as I'm comfortable with their Y class service and I consider that I get good value for my money.
For my trips to the United States I've been buying either a B or Y class ticket on UA and then use my points to upgrade to business at the lower rate. I view this arrangement as essentially purchasing a discounted business class ticket.
