What happens in the first 24 hours of a delayed bag?

File PIR at the airport. Airline may provide a basic amenity kit. Start tracking essential expenses. Ask when the bag is expected.

What expenses will the airline reimburse?

Reasonable emergency purchases, typically $50-200 per day for 3-5 days. Toiletries, basic clothing, urgent medical. Keep receipts.

When is my bag considered lost?

After 21 days of unsuccessful tracing, most airlines and the Montreal Convention classify the bag as lost. Switch to lost baggage claim at that point.

How much will the airline pay for a lost bag?

Up to $3,800 domestic US, about $1,700 USD international. Declared value can extend to $5,000.

Will the airline ship my bag to me?

Yes, if located. Most airlines courier delayed bags to your hotel or home once found. Request this at the PIR stage.

What if the airline lost my bag at a layover?

The operating carrier on the segment where the bag was lost is typically responsible. File the PIR at your final destination with the airline where the bag should have arrived.

Do I need to reach 21 days to claim loss?

For Montreal Convention purposes, yes. For US domestic, some airlines allow earlier loss filing if the bag is clearly unrecoverable. Check the specific airline's policy.

What if the airline stops tracing before 21 days?

If the airline officially closes the trace as "unrecoverable," you can file the loss claim immediately. If they just stop responding, escalate to DOT or credit card chargeback.

Delayed Baggage: 24 Hour and 72 Hour Rules

Delayed baggage 24 72 hour rules dictate what airlines must provide at different points during a baggage delay. Interim expenses begin at 24 hours, formal claim filing at 72 hours, and the bag is considered lost at 21 days. Here are the exact obligations.

The Timeline

Delayed baggage 24 72 hour rules break down as follows under DOT and Montreal Convention standards:

›
0-24 hours: bag is "delayed." File PIR at airport. Essential expenses begin to accrue.
›
24-72 hours: interim expense reimbursement for toiletries, basic clothing.
›
72 hours+: formal expense claim should be filed. Continue tracking.
›
5-7 days: most bags are found by this point.
›
21 days: bag officially considered lost under Montreal Convention.

The 24-Hour Rule

Within the first 24 hours of a baggage delay, airlines should provide essential overnight items (toiletries kit, sometimes a t-shirt). Many airlines offer a small amenity kit for free at the baggage service counter. Beyond that, you pay and submit for reimbursement.

Keep every receipt. The airline reimburses reasonable emergency purchases during delay, typically $50-200 per day for 3-5 days. Toothbrush, shampoo, change of clothes, urgent prescription fills.

The 72-Hour Rule

At 72 hours, the delay becomes serious. File a formal claim with the airline for interim expense reimbursement. Most airlines will issue reimbursement within 14 days of submission.

1
Submit formal claim via airline's baggage claim portal.
2
Include PIR number and all receipts to date.
3
Include a running inventory of items in the bag.
4
Request essential expense reimbursement AND keep the delay claim open for potential loss.

The 21-Day Rule

At 21 days, the Montreal Convention (and most US airlines) officially considers the bag lost. Switch to a lost baggage claim and request full compensation up to the liability cap.

›
US domestic cap: $3,800 per passenger.
›
International cap: about $1,700 USD (Montreal Convention 1,288 SDR).
›
Declared value option: up to $5,000 with declaration fee.

What to Document Throughout

›
PIR number from the airport.
›
All receipts for essential purchases.
›
Communication with the airline (emails, chat transcripts, call logs).
›
World Tracer updates if provided.
›
Item inventory with estimated values.
