SYDNEY, Dec 16 (Reuters) - Qantas Airways Ltd said on Thursday it expected to report a loss before interest, tax, depreciation and amortisation of A$250 million ($179.35 million) to A$300 million for the first half due to months of lockdowns.

The airline said it had boosted its liquidity position during the half through the A$802 million sale of land near Sydney Airport. It expected to have A$5.6 billion of net debt as of Dec. 31, the end of the first half of its financial year. ($1 = 1.3939 Australian dollars) (Reporting by Jamie Freed; editing by Diane Craft)
