I would like to have further clarification about the answer given to a question within the FAQ mentioned in the ISPG 5.11 (page 147). The question concerned the obligation to mention all flight numbers and dates on an invoice of an on-going service.
The reply was as follows:
“To handle the scenario where an invoice has to be raised for a specific flight operating daily, provide only one line item detail to state the Flight details and state only the end date of the month in the field FlightDateTime; Quantity will be stated as the number of days in the month (28/29/30/31)”.
My question is:
1. Does this answer means that for an invoice which charge category is ground handling, and charge code: Passenger handling or Ramp handling for example, we are required to have at least a number of line items details corresponding to the number of different flight numbers operated during a period?
Knowing that in the current invoicing process (non-IS), the invoice is global and attached to only a detail by aircraft type code (so that each line of this detail corresponds to the total amount of handling relative to all flights operated during a period for one aircraft type code).
2. If the reply to my first question is affirmative, and in case of a same flight number operated in two different dates with two different aircraft type code; should we split the invoicing of this flight in two line items details, one for each aircraft code (since it is also a mandatory field)?
