I have two future avios earning bookings and have noticed that one passenger out of the three shows as earning less avios.

I checked the amount of avios that the routes should earn and it seems that although all three passengers are silver the avios shown for one is what would be earned as a blue member.

The exec account numbers are all correct and the accounts all show fine with the same expiration dates which are beyond the travel dates.

One booking is a BA holiday and the other is a flight only booking.

Has anybody come across this before? Do I need to query it or will it rectify itself after the flights?
