The author has obviously never heard of Ryanair whose "ancillary" income is about 25% of it's total revenue and which unlike US airlines doesn't include compulsory items. All of it is from items that are theoretically optional like baggage fees, online check-in fees, excess baggage, booking fees and similar.
