Hello, I have realized a few weeks ago that starting mid last year all my flights bought with weekend card, gave 0 blue credits while they were earning previous years. When i enquired, they said weekend card fares are not eligible for earning blue credits and referred me to this part from general terms "4.8. Some special fares do not grant blue credits and are excluded from the bluebiz Program by Air France and KLM and Participating Airlines. bluebiz earning scales are provided on bluebiz.com."

For me it is not clear at all, they could have specified what special fares mean? was this weekend card fares exlusion something known and i just got luck to get credits for 6 years?
