This is the clause that I presume AXA are referring to. They state I didn’t ever arrive at the destination.

a) Baggage delay. £300 per person if Your checked in baggage has not arrived at Your destination
airport within 4 hours of Your arrival;
b) Extended baggage delay. An additional £300 per person if Your checked in baggage has still not
arrived at Your destination airport within 48 hours of Your arrival.
