A política de fiscalização do DOT sobre tarifas erradas
On April 25, 2011, the Department of Transportation issued a final rule on enhancing airline passenger protections which included a provision prohibiting airlines and other sellers of air transportation from increasing the price of air transportation after a purchase has occurred (the post-purchase price increase prohibition). See 14 C.F.R. § 399.88. Under section 399.88, a purchase occurs when the full agreed upon amount has been paid by the consumer.
On June 15, 2012, the Enforcement Office issued Answers to Frequently Asked Questions about the application of the post-purchase price increase rule to mistaken fares. Mistaken fares are offers by an airline or other seller of air transportation to sell tickets for air transportation for a fare that is usually substantially lower than the intended ticket price for the class of service being sold.
Ênfase minha.
A minha interpretação: uma vez que esta não é uma tarifa equivocada, ela se enquadra no 14 CFR 399.88 - Proibição de pós- aumento de preço de compra e AA está no gancho para lidar com a Dragonair. Mas: IANAL e eu nem estamos jogando um advogado na televisão.
