Oil remains the single-biggest challenge for airline profitability. Strong demand gives little hope of significantly reduced prices this year. What is disappointing is the response of the oil industry. Instead of expanding refinery capacity, the oil companies plan to return a quarter of a trillion dollars to investors over the next two years. Airlines alone have contributed $14 billion to this windfall profit. It is time that governments stepped in to encourage investment in new refinery capacity along with research into alternative fuel sources.
