Abstract
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.
