Benchmarking the recovery of air travel demands for US airports during the COVID-19 Pandemic

Airport terminal passenger forecast under the impact of COVID-19 outbreaks: A case study from China

“…To explore the impact of different pandemic control policies, the air passenger traffic trends identified in this study were compared with another study that analyzed airports passenger traffic in the United States during 2020 and 2021 [ 21 ]. Fig.…”

“…However, the recovery rate in China was much higher, with passenger traffic returning to approximately 75% of the max capacity within ten months after the first outbreak. In comparison, the passenger traffic at most analyzed airports in the United States did not recover to 50% of the pre-outbreak level after a year of entering the pandemic [ 21 ]. On the other hand, China's Zero-COVID policy has also caused greater volatility in air travel demands compared to the US aviation market.…”

“…The pandemic has posed a huge challenge for future passenger forecasting. Traditionally, passenger profiles from previous years was considered an important baseline for forecasting [ 21 ]. In many existing studies, historical passenger traffic profiles have been used as the critical predictor of time series traffic forecasts in regression models and machine learning models [ [22] , [23] , [24] ].…”

“…In many existing studies, historical passenger traffic profiles have been used as the critical predictor of time series traffic forecasts in regression models and machine learning models [ [22] , [23] , [24] ]. Additional socioeconomic factors, such as national and regional gross domestic product (GDP), income levels, population, employment rates, and special events, were used to fine-tune the forecast [ 21 , 25 ]. Some studies have also attempted to predict travel demands with unconventional factors such as search engine queries [ 26 , 27 ] and social media data [ 28 ].…”

“…The same situation occurred in 2021 when the airport's annual aircraft movements decreased by 31.93% on the 2020 levels (Figure 2). The COVID-19 pandemic continued to have an impact on the air transport industry in 2021 (Gao, 2022).…”
