I flew from Kaohsiung to Shanghai Pudong on 4/16, can I issue an invoice for reimbursement?

ok, ok, ok

The air ticket itinerary is the reimbursement voucher, there is no invoice

Do you book on Ctrip? Most of them can be checked to provide invoices.

For reimbursement issues, you need to call the Ctrip service hotline 10106666 and transfer to a manual solution. I hope to help you. Welcome to click "Accept"

Hello! <br/>Are you asking about air ticket reimbursement -- Ctrip's air ticket page will prompt, some of which are air ticket itineraries [regular reimbursement forms], and some are overseas air ticket reimbursement certificates [attached screenshots for your reference]

I can send it to you after the trip~
