Supply chain issues will impact air travel in 2023, IATA director general says. Juliette Michel | Afp | Getty ImagesAir travel will be affected by "very frustrating" supply chain issues this year, according to Willie Walsh, director general of the International Air Transport Association, as he discussed the challenges facing the aviation sector this year. And we're already seeing that," Walsh told CNBC's Dan Murphy. A scarcity of air traffic control staff is also likely to be a problem in 2023, Walsh said. "The challenges we expect to see in the short term are outside of our control, and they principally relate to shortages, in resources in air traffic control," Walsh said.
