MINNEAPOLIS, Feb 14 (Reuters) - Low-cost carrier Sun Country Airlines said on Thursday that it had agreed to sell some of its assets to a new group investors as it seeks to suspend bankruptcy proceedings brought against it by three creditors last month. Sun Country Airlines, a privately held carrier, said it had filed a motion with the U.S. District Court in Minneapolis to suspend proceedings related to the involuntary Chapter 7 bankruptcy case. The airline said that it had received a letter of intent from MN Airlines, LLC to purchase certain assets, including aircraft parts, office equipment, technology licenses and the right to use Sun Country Airlines name. After the court has approved the transaction, MN Airlines plans to request that the U.S. Department of Transportation transfer Sun Country Airline's operating certificate to the new ownership. U.S. Bank will sell the other assets not acquired by the new company, it said. "This is the best possible solution for Sun Country, U.S. Bank and the new owners," said President and Chief Executive David Banmiller. Sun Country said the process will not impact the airline's planned scheduled operations, which include service to 12 cities starting at the end of February.
