Back in April, the IATA had predicted the drop to be just 46%. 修正后的基线预测是，2020年国际客运量将比2019年下降55%。今年4月，该机构曾预测下降幅度仅为46%。 Passenger numbers are expected to rise 62% next year, but will still be down almost 30% compared to pre-Covid times, with a full recovery to pre-pandemic levels not on the cards until four years from now. |
