Aer Lingus Dog Policy: Can Your Dog Fly in the Cabin or Hold in 2026?

The Aer Lingus dog policy is simple: pet dogs cannot fly in the cabin. As of October 2026, Aer Lingus carries household dogs and cats only in the aircraft hold, and they must be booked through a pet agent (IAG Cargo for North American departures). Trained service dogs for passengers with a disability or reduced mobility fly free in the cabin. Pets are refused at passenger check-in, on Aer Lingus Regional flights and on A321neo LR aircraft.

In short, the Aer Lingus dog policy is the set of rules Ireland's flag carrier uses to decide whether, where and how a dog may travel on its flights. Those rules sit on top of separate government entry rules set by Ireland's Department of Agriculture, Food and the Marine (DAFM), the European Union and, for US-bound flights, the US Centers for Disease Control and Prevention (CDC). This guide covers both layers and cites the primary source for each rule.

Can dogs fly in the cabin on Aer Lingus?

No, unless the dog is a trained service dog. On its disability assistance page, Aer Lingus (2026) states that it only accepts dogs as service animals in the cabin. It also states that "pets, emotional support animals or service animals in training will not be accepted for travel on board any Aer Lingus aircraft."

This differs from some European airlines that allow small dogs in a soft carrier under the seat. Aer Lingus has no small-pet cabin option, so a chihuahua is treated the same as a labrador: it flies in the hold.

How pet dogs travel on Aer Lingus: the hold, via a pet agent

Aer Lingus's baggage information page (2026) sets out its general animal rules:

• Pets must be booked with a pet agent and are carried in the aircraft hold.
• Animals presented for transport at passenger check-in "will not be accepted under any circumstance."
• Only household pets (cats and dogs) are carried on transatlantic routes in either direction.

IAG Cargo, the cargo arm of Aer Lingus's parent group, confirms on its Live Animals page (2026) that "Aer Lingus only accepts cats, dogs and invertebrates." It also says all live animal bookings, except pet bookings from North America and the Caribbean, must be made through a freight forwarding company with animal experience. IAG Cargo points owners to the International Pet and Animal Transport Association (IPATA) or the Animal Transport Association (ATA) to find a pet relocation agent.

IAG Cargo booking specifications

IAG Cargo (2026) lists these specifications for live animal shipments:

• Booking window: up to 14 days before departure, or up to 6 weeks for USA and Canada bookings.
• Check-in cut-off: live animals must be checked in 4 hours before departure, subject to station capability.
• Standards: shipments are handled under the International Air Transport Association (IATA) Live Animals Regulations (LAR).
• Breed restrictions: "certain cat and dog breed restrictions apply."

Extra rules for North America to Ireland

Aer Lingus (2026) adds these conditions for pets flying from North America to Ireland:

• Bookings go through the North American Pet Desk run by IAG Cargo.
• Animals cannot be shipped from North America on Fridays or Saturdays.
• Dublin must be the final destination for every animal leaving North America on Aer Lingus.
• A pet arriving from the USA must have a DAFM compliance check booked before arrival.
• Pets must be accompanied by their owner or an authorised person.

Where Aer Lingus will not carry dogs at all

Aer Lingus (2026) names two situations where no pets are carried, whatever paperwork you have:

1. Aer Lingus Regional: if any part of your journey is on an Aer Lingus Regional flight operated by Emerald Airlines, pets are not permitted.
2. A321neo LR aircraft: no live animals are carried because "the cargo holds are not ventilated." Aer Lingus uses this aircraft on some transatlantic routes, so check the aircraft type on your flight before booking a pet agent.

Aer Lingus service dog policy

Aer Lingus (2026) accepts trained service dogs for passengers with a disability or reduced mobility. A service dog must be "individually trained to do work or perform a task for the passenger's benefit." Rules that apply on all flights:

• The dog must be harnessed, leashed or tethered at all times, and must be clean and well-behaved.
• It must fit at your feet, under your seat or on your lap. If it travels in a kennel, the kennel must fit under the seat in front.
• It may not sit in an exit row or block an aisle. In business class you give up the lie-flat feature so the dog can use the floor space.
• It travels free if it fits the allotted space. Otherwise you may have to buy an extra seat, rebook, or send the dog as a pet.
• Six breeds must be muzzled and led on a leash no longer than two metres by a capable person over 16: American Pit Bull Terrier, Bull Mastiff, Doberman Pinscher, English Bull Terrier, German Shepherd (Alsatian) and Japanese Akita.

Flights within Europe

On European flights, Aer Lingus (2026) requires an Assistance Dog Identification Card from an organisation accepted by, and affiliated to, the International Guide Dog Federation (IGDF) or Assistance Dogs International (ADI). Send a special assistance request at least 48 hours before travel. One service dog per passenger flies free.

Flights to and from the USA and Canada

Passengers flying to or from the USA must submit the US Department of Transportation (DOT) Service Animal Air Transportation Form. If the flight is eight hours or longer, they must also submit the DOT Service Animal Relief Attestation Form (Aer Lingus, 2026). Forms are due 48 hours before departure if you booked 48 hours or more ahead. Up to two service dogs per passenger fly free on these routes.

DAFM (2026) also requires anyone flying into Ireland from a non-EU country with a service dog to give advance notice at least 24 hours before departure. DAFM does not charge for compliance checks on guide and assistance dogs trained by IGDF- or ADI-affiliated organisations, provided the dog travels with an identification card or letter from that organisation.

Irish entry rules every Aer Lingus dog must meet

Aer Lingus decides where a dog sits on the plane, but governments decide whether it can enter the country. DAFM's Pet Travel page (last updated 5 August 2026) says it "has no objection" to pets in the cabin or as excess baggage. It adds that "the ultimate decision on where in the plane an animal travels is up to the airline concerned." All pets entering Ireland must comply with EU Regulation 576/2013.

Step-by-step: preparing a dog to fly into Ireland

1. Microchip first. Use a chip readable by a device compatible with ISO standard 11785, inserted before the rabies vaccination (DAFM, 2026).
2. Rabies vaccination. The dog must be at least 12 weeks old when vaccinated. Wait at least 21 days after a primary vaccination, or 30 days if the vaccine datasheet says so (DAFM, 2026).
3. The right document. EU residents use a valid EU pet passport. Non-EU residents need an EU Animal Health Certificate signed by an official state veterinarian within 10 days of arrival in the EU (DAFM, 2026).
4. Rabies blood test, if needed. Dogs from countries not on the EU's listed-country table need a rabies serological test. They must then wait three months after a successful blood sample (Citizens Information; DAFM, 2026).
5. Tapeworm treatment. Unless arriving directly from Finland, Malta, Norway or Northern Ireland, a vet must give a praziquantel treatment 24 to 120 hours (1 to 5 days) before the scheduled arrival and record it (DAFM, 2026).
6. Advance notice and compliance check. From outside the EU, book a compliance check through DAFM's Advance Notice Portal. Enter only through Dublin Airport, Cork Airport, Shannon Airport, Dublin Port, Ringaskiddy (Cork) or Rosslare Europort (DAFM, 2026).

The April 2026 pet passport change

DAFM (2026) states that "from 22 April 2026, EU pet passports may only be issued and valid to owners whose main residence is within the European Union." This applies to all EU pet passports, including those issued before that date. For example, an American family whose dog already has an EU pet passport from a previous move now needs an EU Animal Health Certificate to fly the dog into Ireland on Aer Lingus.

Where official sources disagree

The two Irish government sources differ on how long an endorsed EU Animal Health Certificate remains valid for onward travel within the EU. DAFM's pet travel portal (2026) says up to 6 months. Citizens Information (page edited September 2024) says 4 months. In both cases the limit ends earlier if the rabies vaccination expires. DAFM is the competent authority and its page is more recent, so confirm with DAFM if your trip depends on it.

Third-party summaries also differ from Aer Lingus's own pages. PetTravel.com lists banned breeds such as Rottweilers, Dogo Argentinos and Japanese Tosas. It also says snub-nosed breeds like bulldogs, pugs and boxers are refused. Aer Lingus's own pages name six breeds under the service dog muzzle rule, and IAG Cargo says only that "certain cat and dog breed restrictions apply." If you own a brachycephalic (flat-faced) or restricted-type breed, get written confirmation from your pet agent or IAG Cargo before booking.

Flying a dog to the United States on Aer Lingus

Since 1 August 2024, the CDC has required every dog entering the United States, including service dogs, to be at least 6 months old, microchipped and accompanied by a CDC Dog Import Form receipt (CDC, 2026). Aer Lingus links to this requirement on its service dog page.

The CDC (2026) says that if the dog travels by air, "you must show the receipt to the airline before boarding." For dogs that have been only in dog rabies-free or low-risk countries in the previous six months, the receipt is the only form needed. It stays valid for six months for repeat entries from the same country. Dogs that have been in a high-risk country face extra requirements, so check the CDC's country list before you travel.

Aer Lingus pet travel vs Animal Passport: not the same thing

Searches for "pet passport" and "animal passport" often get mixed up, so here is the difference. The EU pet passport is an official document completed by an authorised veterinarian. It records a dog's microchip number, rabies vaccination and tapeworm treatment, and Aer Lingus and Irish border officials rely on it under EU rules.

Animal Passport is a different product: a digital animal and livestock identity record built on muzzle biometrics. An animal's nose print is unique, like a fingerprint. A phone captures the nose print, and the record links it to the owner, breed, estimated age, body condition and vaccination history. Age is estimated from a dental photograph with a confidence score, and body condition is scored from 1 to 5 from a side-profile photo. In August 2025, Animal Passport was used during livestock flood rescue in Pakistan so farmers could reclaim animals after paper tags washed away.

Animal Passport is not an EU pet passport, an EU Animal Health Certificate or any government-issued travel document. It does not replace a microchip, rabies vaccination, tapeworm treatment or CDC receipt, and Aer Lingus does not list it as an accepted document. For flights, follow the official documents above. For more on animal identity, see the Animal Passport blog.

Practical checklist before you book

• Check that no leg is on Aer Lingus Regional or an A321neo LR aircraft.
• Contact a pet agent (IPATA or ATA member) or the IAG Cargo North American Pet Desk before buying your own ticket.
• Confirm in writing that your dog's breed and crate are accepted.
• Count back from arrival for the 24 to 120 hour tapeworm window, and remember that weekend vet closures can make it hard to hit.
• Book the DAFM compliance check and keep original, wet-signed paperwork. DAFM says photocopies and digital printouts are not accepted.
• For US-bound dogs, get the CDC Dog Import Form receipt before you reach the airport.
