Quick Start Checklist: What to Do Immediately After Lost Baggage

Act fast in the first 24-48 hours--95% of mishandled bags (3-10% rate industry-wide) are reunited with owners quickly. Here's your 7-step actionable checklist:

Stay at the baggage carousel: Wait until the end; bags can arrive late or on the wrong belt (e.g., Points Guy case of LAX bags rerouted internally).
Go to the airline's baggage service desk: Located near arrivals--don't leave the airport without reporting.
File a Property Irregularity Report (PIR): Get a unique 13-digit code (e.g., LAXAA1234567890). Note the baggage tag number (critical unique ID linking to your flight).
Take photos: Snap your boarding pass, PIR copy, empty carousel, and any tags/receipts.
Describe your bag in detail: Color, size, brand, tags, contents (photos inside/outside pre-flight help).
Get essentials reimbursement: Ask for €50-100/day for clothes/toiletries (keep receipts).
Track online: Use airline app/site with PIR/tag number for real-time status.

Mini case: Travelers from LAX to Adelaide (Points Guy) had bags left behind but recovered via prompt PIR and app tracking.
