How will retro claims be included for the calculation of the entry level?

The calculation is not based on the flight date or issuance date, but on the date that the ticket is added your account overview. So, the same counts for retro claim. Tickets which are not eligible within the bluebiz programme will not be taken into account for the turnover. You can recognize non eligible tickets with 0 blue credits in the account overview, pending tickets will be shown with a dash.
