A bankruptcy court judge has set a date of August 4 to hear arguments related to Hawaiian Airlines’ request to bar Mesa Air Group subsidiary Go! from selling tickets for inter-island travel for one year. The motion for a preliminary injunction, filed in late June, cites Mesa’s alleged misuse of confidential information disclosed during Hawaiian’s 2004 bankruptcy.

The court has set an April trial date for a lawsuit filed by Hawaiian that seeks monetary damages from Mesa. Hawaiian also asked for a 45-day extension of its deadline to conduct further discovery and add other parties to the suit. Meanwhile, the judge in the case denied a motion by Mesa to dismiss the count that would require it to hand over all confidential information in its possession about Hawaiian.
