Only one website refers to earning charts: Flying Blue.
If your flight number starts with an airline code from one of the Flying Blue partner airlines (e.g. AZ 0123) the accrual scheme of that specific partner (in this case Alitalia) will apply, even if the flight is operated by another airline. Please check the relevant airline partner page for more information about the number of Miles you can earn.
