Airline share prices fell 1.5 per cent around the world last month as the United States dollar and oil prices rallied, but are still up 23 per cent on a year ago. Fares are also falling.
International Air Transport Association figures also showed continued gains in the United States and a positive turn-around in Asia Pacific.
"Declines in fuel costs, which had provided a boost to airline share prices in late 2014, are being offset by the strengthening US dollar," the Airlines Financial Monitor said. "For US carriers, the strengthening dollar could hamper international air travel, while for non-US carriers, there could be increases in US-dollar denominated costs."
Crude oil prices had fallen below US$50 a barrel in January, the lowest price seen for the past six years. Since then, there have been two rallies, one currently under way with crude oil prices rising 20 per cent in early May compared with the most recent low in March. Yesterday oil was trading at US$59.19 a barrel.
Air transport volumes continued to expand strongly, as freight tonne kilometres moderated after a spike in February.
