The only class action is to stop flying..They own the business and can charge whatever the competitors will allow them to. Most airlines have been in the red for many years and several are no longer in business. They are having a good year but not cash rich.. Just about every airline except South West has had a recent re-organization. I worked for an airline for 40 years. We bought fuel 6 months to a year in advance. My company is not feeling a windfall right now as they are burning fuel bought on the market almost a year ago. Nothing wrong with a good ole fare war which might be coming in the months to come. Companies will compete for market share in the good times and many times it by reducing yields (lower fares) to gain market...It is market driven...A bit of irony is that my Tickets this year to Mobay were the lowest fare I have paid in 15 or so years.
