How do I get the reimbursement invoice after I bought the air ticket?

Hello, I am hesitant. Many airlines do not issue invoices, or the mailing time for invoices is too long, so the reimbursement by the unit is based on the flight itinerary. The itinerary can be printed at the airline counter at the airport. <br/>If it can help you, please click to accept my answer, thank you.

Some air tickets on Ctrip may not be able to print the itinerary at the airport, you can enter the Ctrip order or contact Ctrip to mail the reimbursement voucher, hope to adopt it~~
