Impact of alliances and delay rate on airline performance

To examine the operational aviation efficiencies in 22 Asian airlines, the airlines were classified into three strategic alliances, and their respective efficiencies assessed using a modified dynamic undesirable meta‐frontier data envelopment analysis model. It was found that (1) average aviation industry efficiency declined from 2014 to 2016; (2) the number of airport input variables and the output delay rate factor were important inefficiency indicators; and (3) only the One World strategic alliance had an increasing technology gap ratio, which indicated that aviation efficiency was continuing to improve.
