Aer Lingus owes you for a lost, delayed or damaged checked bag up to the legal limit for your trip: 1,519 SDR per passenger, about $2,060 at the IMF rate on 10 November 2026, on an international trip covered by the Montreal Convention, as any trip to or from the United States is (Montreal Convention, Article 22(2)). Aer Lingus asks for the written claim within 21 days (its own rule, last checked 14 September 2026); on an international trip the law’s outer limits are 7 days from receiving a damaged bag and 21 days from receiving a delayed one. The limit is a ceiling, not an offer: you recover what you can show you lost, up to it.

This page is general information about baggage claim rules, not legal advice, and it is not a substitute for Aer Lingus’ contract of carriage or advice from a lawyer about your specific claim.
A bag that never comes back is a loss claim, not an expense claim. Aer Lingus treats a bag as lost after 21 days, the same day the Montreal Convention deems it lost on an international trip. From that day the claim covers everything that was in the bag, at replacement cost, up to the limit the law sets: 1,519 SDR, about $2,060 per passenger, on an international trip.
A typical checked bag’s contents come to $1,200 to $3,000 at today’s replacement cost. That is the engine’s planning band (estimate — your itemized claim sets the real number); your itemized list sets the real figure. What you bought while waiting and the bag fee come on top, and the fee does not count against the limit.
Aer Lingus asks for the written claim within 21 days. The law gives 2 years to sue on an international trip, but the claim that gets paid is the one sent in the first weeks, with the file reference, the itemized list and the receipts. When a delayed bag becomes a lost bag explains the switch.

A late bag is an expense claim: what you reasonably had to buy while it was missing, at the receipted amount, in full. Before any receipt is entered the engine plans $50 to $150 a day of essentials; your receipts set the figure, and the reason for each purchase (a wedding, a winter arrival, a week of meetings) is what turns a “clothing allowance” into full payment.
What Aer Lingus says. Aer Lingus has not published an interim-expense rule in a form we could verify on its pages. The rule below binds it all the same on any trip touching the United States.
What the law says. On any flight to, from or within the United States, the Department of Transportation’s position is that arbitrary limits on reimbursing reasonable, verifiable, actual interim expenses violate Part 254 and are an unfair and deceptive practice. A flat daily allowance and a percentage rule are both arbitrary limits. The DOT has fined airlines for exactly that: Delta Air Lines $100,000 in 2010 for a pamphlet that capped delayed-bag expenses at a flat daily amount (order); Lufthansa $50,000 in 2011 for paying half the cost of clothing bought while a bag was delayed (order); Emirates $100,000 in 2011 for paying little or nothing towards the costs of a delayed bag (order). Aer Lingus may not do the same to you.
The clock. On an international trip the written claim for a delayed bag must reach Aer Lingus within 21 days of the day you got the bag back (Montreal Convention, article 31); Aer Lingus’s own window is 21 days. The 21-day rule applies to every Aer Lingus trip to or from the United States.
The bag fee. Under the 2024 DOT refund rule the checked-bag fee is owed back automatically once a mishandled-bag report is filed and the bag is not delivered within 12 hours on a domestic flight, 15 hours on an international flight of up to 12 hours, or 30 hours on a longer one. It is paid on top of the expense claim.

Report damage before you leave the airport if you can, with the bag in hand; Aer Lingus’s own window is within 5 days. On an international trip the written claim must follow within 7 days of receiving the bag. Claim the repair, or the bag’s replacement when repair is not sensible, and anything inside that was damaged; keep the bag until the claim is settled.

Aer Lingus is not a US carrier, so a trip to or from the United States is an international trip under the Montreal Convention; the US domestic figure applies only to a separate ticket on a US airline.
The ceiling is set by law, not by the airline. On an international trip the Montreal Convention caps liability at 1,519 SDR per passenger, about $2,060. On a trip within the United States the DOT cap is $4,700 per passenger. What you actually recover is what you can show: contents at replacement cost plus what you had to buy while the bag was missing, and the bag fee refunded on top when the bag is late enough.
Aer Lingus’s own page states: “"Euro equivalent of 1,519 Special Drawing Rights ... approximately €1,900 as of December 2024" — missing-baggage page”.
The Property Irregularity Report (PIR) is the report you make to Aer Lingus at the airport, at its baggage desk, before you leave the baggage hall; it gives you the ten-character file reference every later step needs. If you have already left, use Aer Lingus’s baggage page or phone line the same day. Under the Montreal Convention the written claim must then follow within 7 days for damage and 21 days for delay, counted from the day you get the bag back; Aer Lingus’s own windows below can be shorter.
The law sets the outer limits regardless: on international trips, a written claim within 7 days for damage and 21 days for delay (counted from the day you get the bag), a bag deemed lost after 21 days, and 2 years to sue. Read our plain-English guide to the Montreal Convention or the DOT rules for domestic trips.

International trip. A bag lost on a Aer Lingus flight into the United States with $2,745 of contents at replacement cost and $251 of clothes and toiletries bought while waiting: the Montreal Convention limit is $2,060 per passenger, so the letter claims $2,060 under the liability rule and adds the $75 bag fee on top, which the limit does not touch. Total demanded: $2,135, with the itemized schedule attached so Aer Lingus cannot argue the list down below the cap.
Delayed three days, then delivered. Two changes of clothes, toiletries and a charger, about $290 with receipts, plus the bag fee once the delay passed 15 hours on an international flight of up to 12 hours. Aer Lingus may not answer with a flat daily allowance; the DOT treats that as an unfair practice on any flight touching the United States.
The figures are the engine’s: the SDR limit at 1.3559 US dollars per SDR (the IMF rate on 10 November 2026), the DOT minimum since 22 January 2025. Enter your own trip and the estimate shows your numbers.
Read from Aer Lingus’s baggage pages on the day of the check:
Its rules bind you only where the law is silent. The first-report windows are real and worth meeting; anything that reads as a lower limit, a category exclusion or a depreciation table does not override the Montreal Convention on an international trip or the DOT minimum on a domestic one.

What you had to buy while the bag was missing, at cost, up to the legal limit: about $2,060 per passenger (1,519 SDR) on an international trip. Keep every receipt; the limit is a ceiling, not a payout.
At Aer Lingus’s baggage desk before you leave the airport: show the bag tag and boarding pass, describe the bag, give a delivery address, and take the ten-character file reference away with you. Aer Lingus’s own rule for a bag that did not arrive is within 7 days. If you have already left, use the baggage page or phone line the same day; the written claim follows within 7 days for damage and 21 days for delay.
1,519 Special Drawing Rights per passenger, about $2,060 at 1.3559 US dollars per SDR (the IMF rate on 10 November 2026), in force since 28 December 2024. Some airline pages still print the old 1,288 SDR; a claim against Aer Lingus should cite the current figure.
Aer Lingus’s own rule is within 7 days. Report before you leave the airport whenever you can; the file reference from that report is what the claim is built on.
Up to the legal cap for your trip: about $2,060 per passenger on an international trip. The amount depends on what was in the bag and what you can show you paid.

After 21 days under its own rules, which on an international trip matches the 21 days the Montreal Convention allows. From that day the claim covers everything in the bag up to the limit, not only what you had to buy.
Aer Lingus’s own rule: the written claim within 21 days. The law on an international trip: 7 days from receiving a damaged bag, 21 days from receiving a delayed one, 2 years to sue, and a bag not delivered within 21 days is deemed lost.
Not on a flight to, from or within the United States. The DOT treats a flat daily allowance or a percentage rule as an arbitrary limit on reasonable, verifiable, actual interim expenses and has fined Delta Air Lines, Lufthansa and Emirates for doing it.
