IdeaWorksCompany, the foremost consultancy on airline ancillary revenues, and CarTrawler, leading global B2B provider of car rental and mobility solutions to the travel industry, recently estimated ancillary revenue at $65.8 billion worldwide for 2021. This CarTrawler Global Estimate of Baggage Fee Revenue identifies baggage as a $20.9 billion component and provides a summary of baggage fee policies for 20 top airlines. Baggage fees have become more important to airlines during the course of the pandemic. This is evidenced by bag fees’ share of global airline revenue growing from 3.7% in 2019 to 4.6% for 2021. This trend applies for the wide range of optional extras that define ancillary revenue. Look for airlines to increase revenue from these activities by expanding flexible pricing and bundled fares and better retailing through online travel agents and mobile devices.
