The International Air Transport Association (IATA) has issued a warning that the new Entry Exit System (EES) in Europe could lead to airport delays of up to six hours during the busy summer travel season. Rafael Schvartzman, speaking at IATA's 82nd Annual General Meeting in Rio de Janeiro, highlighted that delays are already being experienced in countries such as Portugal, Spain, and Italy, with passengers missing flights due to long wait times at border controls. The EES, which replaces manual passport stamping with digital registration for non-EU travelers, is operational in 29 European countries but has exposed significant operational issues, including understaffed checkpoints and unreliable technology. Current processing times could triple, as the EES requires about 90 seconds per passenger. IATA is calling for the EU to keep suspension mechanisms for the EES available beyond September 7, emphasizing the need for better coordination among airports, airlines, and governments. Additionally, the rising costs of aviation, including increased fuel prices, are placing further pressure on the European airline industry, prompting airlines to seek cost-saving measures.
