When will the electronic invoice be sent to the mailbox after it is issued?

Electronic invoices are generally received within 24 hours of working days. If you need a real invoice, you can also send a reimbursement voucher. Tell the staff the specific delivery address when booking a ticket by phone, or write down the delivery address when booking a ticket online. The ticket agency can mail the travel itinerary to the passengers the day after your flight takes off, and deliver it in a week or so in the local area and two weeks or so in other places.
