Like many others flying yesterday our bags remain at T5C (as per AirTags updates in the past few minutes!). Will BA reimburse for any small purchases made whilst awaiting baggage to your home - given the delay being up to 5 days (and World Tracer not even found our bags yet)? We were away for 3.5 weeks and had packed a lot... (lesson in there somewhere!) - unlikely we would bother to claim but more of an academic question.

Very much first world 'problem' compared to those away from home!
