A delayed or missing bag is stressful mostly because people don’t know what steps actually help versus what just feels productive. Here’s the order that actually matters.
1. Report it before you leave the airport, not later
File a report at the airline’s baggage service desk before leaving the arrivals area, even if a long line makes it tempting to sort it out later online. You’ll need the claim number and a description of the bag, and doing this in person at the airport creates the clearest record.
2. Get the claim number and ask about an immediate expense allowance
Many airlines will cover essentials — toiletries, a change of clothes — while your bag is missing, but you often have to ask rather than being offered it automatically. Keep every receipt for anything you buy, since airlines generally want documentation to reimburse these expenses.
3. Check what your credit card or travel insurance already covers
A number of travel credit cards and travel insurance policies include baggage delay coverage that kicks in after a set number of hours, separate from whatever the airline offers. It’s worth checking this before assuming you’re paying out of pocket for everything.
4. Track it yourself if the airline’s system is slow to update
Airline bag-tracking portals aren’t always current, and a follow-up call or an in-person check at the baggage desk sometimes surfaces information the app hasn’t caught up to yet. If your bag has a tracker of your own inside it, that can also narrow down where it actually is.
5. Know when to escalate and ask for compensation
If a bag is missing for an extended period or permanently lost, airlines have set compensation processes, and international flights are governed by specific liability limits under aviation treaties. Keep your claim number, receipts, and any correspondence together, since you’ll need them to file a compensation claim if it comes to that.
The short version
Report the bag missing at the airport before you leave, not from home later. Ask specifically about an expense allowance and keep every receipt. Check your credit card and travel insurance for baggage delay coverage you may already have. Follow up directly if the airline’s tracking seems stale. And know that a permanently lost bag has a real compensation process, so keep your paperwork together.
