Predatory Pricing
A company engages in predatory pricing when it sets the price of its goods very low in order to eliminate its competitors and prevent new companies from entering into the marketplace.
First, it's very tough to prove. Usually it involves pricing below contribution margin, a tell tale sign a company may be engaged in predatory pricing. Unfortunately for Uair, most of the LCC have the cost structure to cover their variable costs at very low fares. Otherwise, you cannot simply punish firms for being more efficient, as efficiency is not predatory.
I have to admit, its quite ironinc and slightly asmusing seeing these large carriers drop the P word on the LCC's.. Its the epitome of the pot calling the kettle black.
