I have the FB Gold Amex for many years, my anniversary date is in April. One month ago, they charged me as expected with the annual fee. Early May, they credited my FB account the annual 30XP, which I don’t care about because I am Plat for life. But I just looked at my FB account to see if the monthly miles linked to my expenses were posted. They were, but there is also a line « Flying Blue Amex Gold card bonus : 20,000 miles - 0 XP - 0 UXP »
Certainly a nice surprise but what is this ? 1st time I have this in 23 years of subscription of this card. Is that something we will have every year ?

. Anyone else had this ?
