Asia Pacific airlines reported continued expansion in international passenger demand in Jun-2011, although international air freight markets softened further during the month, according to data released by the Association of Asia Pacific Airlines (AAPA). The outlook for the second half of 2011 remains “reasonably positive” AAPA noted, with premium demand remaining strong on many business routes and Japan traffic starting to recovery. AAPA however cautioned over the uncertainty related to the strength of the global economic recovery and oil price volatility.
