There are several methodologies to evaluate the
quality of tourism services. Research instruments have
been developed over the years to evaluate the concept of
quality and consumer satisfaction (Hudson, Hudson, &
Miller, 2004). Some of them are based on questionnaires
that ask people about some attributes of these services.
These results are subjective and may be used as an
approximation to estimate customer satisfaction; however,
there is a need to make valuations about the level
of airport services through a more objective approach
according to normally accepted standard parameters.
This can be done using mathematical techniques (Muller
& Gosling, 1991).
