I've read in a UK magazine that American Express Gold Card members who are members of the International Airline Programme can secure upgrades to business when paying full-fare economy, but when I asked American Express in the US about this program, they said it only allows companion fares. But just now I saw a reference to the possibility of upgrades through the International Airline Program in the Inside Flyer article about upgrades. Does anyone have any idea if this program exists, or how it works? Is it not available to US cardmembers?
