Hello MP readers, as we know, the majors have implemented a new pricing method for multi-city itins. For those who haven't been following the AA/DL/UA boards, the summary is that multiple city itins are now subject to new conditions that prevent them being priced as the sum of one-way pricings (as they have been for decades previously). This change was a. not announced anywhere and b. occurred simultaneously across all three majors. This phenomenon has been reported on AA, DL and UA boards over at FT. DL: http://www.flyertalk.com/forum/delt...-comment-change-pricing-multi-city-trips.html Note the screenshots from a poster's Concur screen showing the warning about revisions to multi-city pricing and its economic impact on businesses. AA: http://www.flyertalk.com/forum/amer...going-aa-multi-city-high-pricing-tickets.html UA: http://www.flyertalk.com/forum/united-airlines-mileageplus/1754289-multi-city-pricing-issues.html The known facts indicate this action is potential collusion and that it warrants anti-trust investigation and perhaps, intervention. I am filing a formal complaint with the DoT, but also with FTC, on the grounds that this activity is clearly collusion for the purpose of market manipulation. I believe that it is collusion because a. the chronology and SIMULTANEITY across carriers who control > 80% of the US civil market suggests that this change has been illicitly coordinated and that b. the change has the effect of controlling the market and increasing prices irrationally for consumers. In case there are people who think, why can it matter? and can/will the regulators actually do anything? check what happened in the 1980s to Bob Crandall - former CEO of AA - who engaged in illegal conversations with his counterpart at Braniff regarding pricing. That case proves that the agencies CAN act against such market manipulation. http://www.nytimes.com/1983/02/24/business/american-airlines-target-of-us-suit.html Now, WILL they? Well...in your hands.... One complaint won't do it, but many hundreds - or thousands - will have an effect. This is a serious matter. This really matters because the three US majors are now - in a tacitly coordinated way - probing the regulatory frontier with their collusion to manipulate market pricing. At this point. They need to be called out. Now. Otherwise, it will not stop. If you agree, draw attention to this posting including on FT - remember, I am censored over there, it is *mejor en su clase* indeed But even if you don't like my postings, you will see the danger this action presents to a competitive air transport market in the US. Act now if you value competition at all.
