Two recent and conflicting data points (AF Plat pax travelling with ITA-operated and marketed flights):
- for a trip in February 2024, miles and XPs were automatically credited 48hrs after my flights (prior to the trip, I had called ITA assistance to have my FB number registered)
- for a trip in May 2024, miles and XPs were missing, FB first rejected my request submitted 2 days after the flights and said they cannot do anything before 8 days, and funnily they accepted by second request submitted 6 days after the flight (my FB number had been registered when buying this ticket, as ITA website seemed to have improved with this new functionality between my two experiences).
