I just have had my first black Friday sale credited. I received even more miles than anticipated.. 😁
AMS-ATH-SKG in U comfort flex (I am gold, so +20% award miles)
AMS-ATH: 1355 tier, 11382 award
ATH-SKG: 500 tier, 4200 award
I received 8,4x the award miles compared to the amount of tier miles, whereas I was expecting 6x * 1,2x. I think perhaps the promotional miles are in addition to the normally credited miles.. 👍 (that would indeed yield 8,4)
