If you need to arrive at the site in advance for the training activities, you can apply to the organizer for reimbursement of tickets. Usually, the organizer will conduct an audit according to the relevant regulations of the company. If you meet the reimbursement conditions, you can get subsidies. However, the specific reimbursement details need to refer to the company's internal regulations. I suggest you know it clearly in advance so that you can apply for reimbursement better.
