Ryanair Holdings Plc said that any tariff cost would be on Boeing Co. to bear, as the Irish budget airline demanded a return to a no-duties regime that that has governed the industry for close to half a century.

Ryanair Holdings (NASDAQ:RYAAY) (OTCPK:RYAOF) on Monday asserted that any tariff-related costs should be absorbed by Boeing (NYSE:BA), as the Irish low-cost carrier firmly called for a reinstatement of the long-standing no-tariff framework that has underpinned the aviation industry for nearly 50 years.
