ASQ/ACI is the only survey measuring passenger's satisfaction while they are at the airport. The survey was carried out at 300 airports all over the world via questions completed by passengers who judged 34 performance indicators (access, check-in, security, layout, shopping, bars and restaurant, etc.). Each airport uses the same methodology, creating an industrial database that enables benchmarking. ACI's Airport Service Quality programme also has a feature to facilitate the sharing of best practices between airport operators.
