Methodology and Purpose of the ACE Survey:
The surveys are completed by Air Cargo World subscribers located throughout the world. Airlines are rated by readers identified as freight forwarders; airports are rated by readers identified as airline employees, freight forwarders, cargo agents, and 3PLs. The purpose of having two survey groups is to ensure the integrity of having actual customers rate their service providers, rather than opening up the survey to the general audience.
The survey asks participants to rate the airline(s) or airport(s) with which they have conducted business in the prior 12 months. Using a scale of 1 to 5 – with 5 being the highest – respondents are asked to rate those qualifying airports or airlines in the three areas of measurement noted above.
The airlines are grouped by annual freight tonnes carried, according to IATA data, and the airports are grouped by regional location and sub-grouped by annual tonnage handled. These groupings are done within the survey analytic structure and are not known to the person who is rating the airline or airport. The purpose in grouping the airlines and airports is to provide an equitable rating system in establishing the surveys’ results.
The average rating for each measurement is calculated within each group, and that average is indexed to a value of 100. Ratings for airlines and airports are presented as an Indexed Score, relative to the average, to allow for easy comparisons. Scores greater than 100 represent an above-average performance. Scores of 100 represent exactly average performance. Scores less than 100 represent below-average performance.
