Ann: Airline AI solution launched with Microsoft, page-27

Can anyone here tell me what the staff costs are attributed to? 
Is it sales or customer support, executive salaries across the different regions?

The quarterly costs seem to be rising within this area. No major increase in advertising or marketing, or product and manufacturing. 

It’s the only thing holding me back from changing sentiment: very interested- not held.

Positive is that LVT has its foot in the door in the right disrupting sector of AI and in the right backing company in Microsoft.
