Expedia has been quietly testing flight reviews for the past 18 months - with results illustrating that they could become as important as hotel reviews. Expedia has discovered there is not only enthusiasm by consumers to share their feedback from a flight, but the presence of reviews in results has a clear impact on conversions. The company has already had 3 million flight reviews since the test began in early 2014, with it expected to reach over 5 million by the end of 2015. Consumers in the US are invited to leave a review of their flight via a post-trip email, similar to those issued for hotel reviews. The idea is to give as much information as possible to help customers make better flight choices. Flight reviews are becoming an increasingly important part of the purchase decision, with travellers looking to learn not only the difference in products and facilities on board but the quality of the overall experience.
