To be a clerk, how to book train tickets and plane tickets?

If your company has a cooperation agreement with some suppliers who book air tickets, you can call them directly, and then tell them what day and time you want, and then ask them to apply for the lowest discount for you. If you are not sure, you can reserve this air ticket first, and then call them to help you out when you are sure. You don't need to pick it up yourself, but you need to have the flight information you booked sent to the passenger's mobile phone by SMS. That's enough. Finally, the passengers just need to check in at the airport. It's simple. You can try.
