Making Sense of Air Fares

There is a suggestion that airlines have realized that the spread has gotten too large between last minute business and plan ahead vacation buyers. Southwest and other low cost carriers have attacked the middle section with simpler plans and now -- "Despite what you might think, the impact of low-fare airlines on major carriers isn’t in the lowest fares: It’s in the middle range. A traveler can book three days out on Southwest or Britain’s EasyJet and get a mid-price fare, while a full-fare ticket on the competition costs hundreds more."

Of course, someone thinks they have a newer better model that may fix that.
