Reuters exclusively reported that Spirit Airlines was pressing JetBlue Airways to appeal a decision by a federal judge to block the tie-up between the sixth and seventh largest U.S. airlines. Spirit told JetBlue that their deal contract required them to exhaust legal options to complete their deal, and that they should appeal the judge’s ruling, sources told Reuters. JetBlue said subsequently that it would file the appeal together with Spirit, in accordance with the requirements of their merger agreement.
