Abstract: The purpose of this study is to forecast the arrivals of international tourists to three major cities: New York, Singapore and Dubai, based on data procured before the COVID-19 pandemic was declared. We apply four distinct forecasting models: two conventional linear models, namely exponential smoothing and SARIMA, and two advanced non-linear models, specifically the Prophet with Fourier transformation and LSTM utilising deep learning techniques. We used monthly arrival data spanning from January 2001 to December 2017. Our findings reveal the superior forecasting performance of LSTM neural networks over dynamic regression with Fourier, resulting in a substantial reduction in error rates ranging from 20% to 60%. Notably, SARIMA outperformed conventional models in certain assessments. Despite their accuracy, these models retain generalisability, which is also a significant advance for practitioners such as policymakers and decision makers. This enhanced forecasting capability empowers decision-makers to plan infrastructure and human resource requirements with increased confidence in future endeavours.
