How a legal entity can buy airline tickets and get documented proof of expenses for the accounting department
Credit card payment
Tickets are paid for by a credit card.
Documented proof includes:
itinerary/e-ticket sent by e-mail after a ticket is purchased and/or printed on an ordinary printer
a bank statement confirming the payment for the electronic ticket with a payment card.
Please note that passengers cannot obtain copies of the boarding passes. Therefore, it is strongly recommended that you keep the boarding passes for your flight!
