Skytrax (originally known as Inflight Research Services) is a United Kingdom-based consultancy which runs an airline and airport review and ranking site. In 2012, the online investigations company KwikChex filed five complaints with the UK Advertising Standards Authority. The authority upheld all five complaints and Skytrax agreed to modify some promotional wording. Questions have also been raised about Skytrax' objectivity and methodology.
