How airline fees have turned baggage into billions

Airlines have profited billions from check-in luggage fees, prompting frustration among travelers who now opt for carry-on bags to avoid extra charges. With US airlines making $7.27bn from baggage fees in 2020, demand for small carry-on suitcases is on the rise. The global airline industry expects to generate $145bn from various additional fees this year, with politicians calling for a review of these "junk fees." Social media influencers like Chelsea Dickenson are contributing to the trend by creating content about packing hacks and luggage that meets airlines' size restrictions.
