The new guidelines of the ECDC in cooperation with the EASA are a sounding board for governments: They rule out an increased risk of infection spreading among air travelers and recommend the abolition of the quarantine requirement for incoming passengers. The aviation industry is experiencing its greatest crisis since the outbreak of the pandemic.
