I had this on a WTP booking recently. It was quite pricey as short trip booked late but booked through corporate travel agent which I assumed was why I got the original number of avios rather than avios based on spend. Does that sound right or should I query?
I'd query - most of my travel is booked via a corporate travel agency, and in the past I've gotten the avios based on spend, hence why this one was weird for me
