I just wrote mail to Flyingblue (
[email protected]) send them my ticket with ITA Airways (FCO-RUH ) 20.2.2025-24.2.25 and get the answer from them :
Thank you for having us provided the ticket.
I can confirm to you that this ticket is eligible for Miles and XP accrual. The only thing to bear in mind is, that we will be able to credit the ticket starting the 14th day after the day of the flight. Therefore, we will be able to credit both flights starting from the 10 March 2025.
Thank you for your understanding.
