Delta and Virgin are requesting that the deadline be extended by three weeks, to 13 October, explaining the agency "identified a number of concerns" that the two companies "believe require specific and detailed responsesthe additional time will assist the development of a more complete record, and enable the applicants to address the issues identified".
The joint venture, initially proposed in July 2009, includes Delta, and Virgin carriers Virgin Blue, V Australia, and Pacific Blue. Polynesian Blue is not part of the proposed arrangement. The joint venture received approval from Australian regulators in December.
