I have just achieved BAEC Silver after the 4th leg of a 6 leg trip. Clearly it takes time for the app to show the new status, but I see that I have only been awarded avios for the last 2 legs at the Bronze rate.
Should I expect the last 2 legs to miraculously be increased to the silver rate, or should I chase it up, or is it one of those anomalies that doesn't work quite right?
