Booking flights through online travel companies (OTCs) is becoming increasingly popular. In order to improve profits, OTCs often suggest additional optional auxiliary services, such as security insurance, a VIP lounge or a pick-up service, to passengers. In order to promote the sale of auxiliary services, these can be selected as a default when passengers purchase a flight. However, if a passenger does not want to buy these services, he will have to cancel them himself, which can result in a negative user experience. Therefore, a personalized auxiliary service recommendation approach is proposed (IR-GBDT), which is built on the Gradient Boosting Decision Tree (GBDT) model. GBDT is also applied to mine the interrelationships between services so that a service package is finally recommended. The experiments on a real dataset which includes 6-month’s of flight order data shows that our model has improved performance compared to the others. abstract environment.
