All during 2018, the team at IdeaWorksCompany researched the top ancillary revenue producing airlines and the most generous frequent flier programs, and issued reports that described the industry’s service innovation and product development; as well as offering practical advice for airline management teams.  The culmination of this work is the 2019 Airline Ancillary Revenue and Loyalty Guide. The 270-page Guide includes every published report and survey issued by IdeaWorksCompany during the year and is comprised of four sections: 1) an abbreviated version of the Worldwide Report of Reward Availability from 2018, 2) the full collection of three research papers from IdeaWorksCompany, 3) the complete Worldwide Report of Ancillary Revenue based upon 2017 airline financial disclosures, and 4) summary of results from the 2018 Long-Haul Business Class Rewards Briefing (for American, Delta, and United airlines).
