The turbulence in airline stocks is yet to ease as news of fresh production cuts and calming trade concerns sent oil prices surging on Monday.

U.S. airline shares have traded closely with fluctuations in oil prices over the past few months, especially after several carriers were forced to trim their profit outlook citing soaring jet fuel costs that pressured margins. When the surge was followed by a sharp drop in oil prices, several analysts predicted that the airlines stand to see a material earnings upside in the fourth quarter and next year.

The S&P Supercomposite Airlines Industry Index dropped as much as 1.1 per cent on Monday, while the broader S&P 500 Index gained 1.5 per cent. The top decliners in the airline index included Hawaiian Holdings (HA.O), American Airlines (AAL.O), SkyWest (SKYW.O), JetBlue (JBLU.O) and Delta (DAL.N).

Canadian airline stocks were only marginally down as of 11:25 a.m. on Monday. Air Canada (AC.TO) was only 3 cents in the red, down 0.10 per cent at $28.97. WestJet (WJA.TO), meanwhile, was also down 3 cents, or 0.15 per cent, at $20.58.

“It’s unclear where oil prices go from here, but at current levels the industry collects a US$6 billion free cash flow windfall,” Buckingham Research Group analyst Daniel McKenzie wrote in a note to clients. McKenzie said the drop in airlines’ unit revenue that typically follows a collapse in oil prices was unlikely as demand remained strong, and the industry’s pricing structure was more dynamic due to implementation of basic economy fares and better segmentation.
