CHICAGO, Dec 12 (Reuters) - United Airlines Chief Executive Officer Oscar Munoz said on Wednesday he was "not concerned" about the future of the No. 3 U.S. carrier's joint venture with Colombia's Avianca Holdings and Panama's Copa Airlines.
The comment followed news on Tuesday that a separate carrier, Avianca Brasil, had filed for bankruptcy protection. Avianca Brasil is owned by holding company Synergy Group, which also controls Colombia's better-known Avianca Holdings.
United extended a $456 million loan to Synergy Group last month as part of its planned joint venture.
