Worldwide airline share prices rose five per cent in May compared with the previous month, according to IATA’s financial monitor. The gain was largely attributed to US airline performance despite its passenger yields declining during the first quarter of 2014. IATA also noted weakness in the Asia Pacific market, which it linked to Chinese carriers and the depreciation of the Yuan. The number of available seats rose in April as new aircraft were delivered and old ones came out of storage. Despite the availability of seats, IATA forecast that April’s pick-up in passenger demand should help restrict any downward pressure on aircraft utilisation rates. Air freight continues to be “moderate” with freight load factors making little improvement in 2014, IATA said.
