There is a serious traffic jam on the way to the airport. What should the tour guide do?

If the guest is delayed due to the travel agency, the travel agency shall bear the responsibility. If the tour guide has informed the guests of the departure time in advance, and the guests delay on their own, and the flight and other means of transportation fail to arrive in time, the travel agency shall assist in returning, changing and signing, and arrange the guests to travel, but the losses arising therefrom shall be borne by the guests themselves. Therefore, when sending a tour group, the tour guide must estimate the time in advance and inform the guests to leave in time.
