On Dec. 22, Flying J Inc. announced it, along with certain subsidiaries, had filed voluntary petitions to reorganize under Chapter 11 bankruptcy, which will allow the company to address near-term liquidity needs brought about by the precipitous decline in crude oil prices coupled with the disruption in credit markets.

The filing includes Flying J Inc. and its Big West refining and Longhorn Pipeline subsidiaries. Flying J’s financial advisor is The Blackstone Group L.P. and the legal advisor is Kirkland & Ellis LLP.

All of Flying J’s operations, including approximately 250 travel plazas and fuel stops, are open and serving customers in the normal course of business. The company plans to continue normal business operations as it moves through the reorganization process.
