A major focus of the baggage tracking MVP was designing for the unhappy paths, the moments when guests are still waiting for their bag, unsure where it is, or it is not where it should be and emotions run high. Because our data was limited to intermittent scan events, we had to plan for situations like missing or delayed scans, bags arriving on a different flight, re-routes, tight connections, early or late arrivals, and handoffs between airports or teams where visibility can drop. The experience needed to acknowledge uncertainty without creating false confidence, clearly distinguish “no new scan yet” from “problem detected,” and provide the right next step at the right time, from reassurance and expectations at the carousel to escalation guidance and claim filing when thresholds are met. Copy, hierarchy, and timing were carefully tuned to reduce panic, avoid blame, and keep the guest oriented with a simple path to help when things go wrong.
