Marketing expense went up. Why?

[JumboShrimp]

Ok, I did not add any new destinations, I did not add any new campaigns.  But my marketing spending went up about 30% from previous week to current week.  Any explanation for that?

The only thing other than adding fights on existing routes was to add first a/c with business class to forerly all Y configured fleet.  Is that thing alone responsible for 30% jump in marketing expenses?
