FOR a president elected on a populist campaign message, Donald Trump is not doing much to make himself popular with flyers in America. On December 7th, the Trump administration announced that it was withdrawing a regulation proposed under Barack Obama to require airlines and other plane-ticket sellers to disclose baggage fees when customers begin the process of buying tickets. Airlines already have to display checked baggage fees on their websites. But the Obama administration’s proposal would have forced them to do so up front in the shopping process, so that travellers could compare the fees for various airlines and routes when choosing their itineraries. Mr Trump is also scrapping another Obama-era proposal to require airlines to report to regulators how much money they make from add-ons such as paid carry-on bags and seat selection.
