In short (UK): For most international flights, delayed, damaged, or lost checked baggage is covered by the Montreal Convention — airlines can be liable up to a set SDR limit per passenger. Get a PIR at the airport, keep tags and receipts, claim in writing within short notice periods. This is general guidance, not legal advice.
Missing luggage ruins a trip — but you are not stuck with “sorry, nothing we can do.” This guide covers the core rules — not a full claim pack. For a personalised plan and letter from your booking details, use Refundly.
Delayed, Damaged, or Lost
| Situation | Typical first step | What you often claim |
|---|---|---|
| Delayed bag | PIR + emergency purchases | Reasonable essentials + delivery costs |
| Damaged bag/contents | Photo + report ASAP | Repair/replacement within liability limits |
| Lost bag | Follow up until “lost”; full claim | Contents + bag, evidenced values |
Liability is usually limited (Montreal Convention SDR cap per passenger unless you made a special declaration / paid for higher cover). Travel insurance may sit on top — claim both routes carefully so you do not double-recover the same loss.
What to Do Next (High Level)
- Report at the airport — get a PIR / reference before you leave.
- Keep boarding pass, baggage tags, and booking confirmation.
- Buy only reasonable essentials and keep every receipt.
- Photograph damage; list contents with approximate values.
- Send a written claim with deadlines; escalate if ignored or underpaid.
PIR date, spend receipts, and claim deadlines decide many baggage disputes
Notice Periods and Evidence
Convention-style rules use short written-notice windows (damage often within days of receipt; delay claims also time-limited). Do not wait for the airline’s chat to “get back to you.”
Checklist for your claim: flight numbers and date; PIR reference; bag tag numbers; itemised list + receipts/valuations; emergency purchase total; remedy wanted (payment, not only a voucher).

Airline Offer vs Full Claim
Interim expenses or a goodwill voucher can help day one — they do not always settle the whole Convention claim. If the bag is later found damaged or never returns, update the claim in writing.

Final Tip

Common questions
Short answers to common questions on this topic.
- What are my rights if an airline delays or loses my bag?
- International carriage is largely covered by the Montreal Convention. Airlines can be liable for delayed, damaged, or lost checked baggage up to a liability limit (expressed in Special Drawing Rights). Claim in writing with receipts and the PIR reference.
- What should I do at the airport when my bag does not arrive?
- Report it before you leave — get a Property Irregularity Report (PIR) or equivalent reference, keep baggage tags and boarding proof, and note essential items you need to buy. Photo evidence of damage helps for damaged bags.
- Can I claim for clothes and toiletries I had to buy?
- Often yes for reasonable emergency purchases while a bag is delayed — keep every receipt. Airlines sometimes offer interim expenses policies; Convention liability still frames what you can pursue if they refuse fair costs.
- When is a delayed bag treated as lost?
- If it has not been found after a sustained period (commonly framed around 21 days under Montreal rules), treat it as lost and claim for contents with evidence of value. Deadlines for written notice are short — act promptly.
- What if the airline offers a low voucher?
- You can reject an inadequate offer. Put a full itemised claim in writing with receipts or valuations, then escalate via the airline complaints process and ADR/CAA-style routes if unresolved.
