May I book flights with expired passport details while waiting for the collection of new passport?
@fad are you saying that the passport you have on your SAP Concur Travel profile is expired? If so, I believe you can still book your flight. If you are flying internationally, the system might pop up a message about your expired passport, but I think you can still complete the booking. I've never tried it, so I think there is really only way to find out for sure. 🙂
