New York City → Europe

Flying with a dog from NYC to Europe

The airport does not change the health rules; the first country where you enter the EU does. Start with destination paperwork, then compare the operating airline from JFK or Newark—not just the marketing carrier on the ticket.

Rules and airline policies last reviewed 21 August 2026

Route alert

A ticket to “Europe” is not one legal route. France, Germany and the Netherlands use the common EU framework, while Ireland adds advance entry/compliance logistics and tapeworm treatment for dogs. Great Britain is not in the EU and requires air-arriving pets to travel as cargo.

Best first decision: Choose first border-entry country
Small-pet cabin: Usually carrier-fit or 8 kg combined, airline dependent
EU paperwork: USDA-accredited vet + APHIS endorsement
UK-bound air: Cargo, not ordinary cabin travel

In the right order

Your step-by-step checklist

1
Before comparing fares
Pick the actual first entry airport
A Paris connection that clears the EU border is a France entry, even if the final holiday is elsewhere. Confirm transit and inspection handling.
2
At least 21 days before a primary dose
Complete the microchip/rabies sequence
Have the USDA-accredited vet scan the microchip before vaccination and record the exact number consistently.
3
Inside the official window
Build the certificate timeline
Use the live APHIS destination page, correct 2026 form and endorsement timing. Do not use a generic online template.
4
Before paying
Compare operating airlines
KLM, Air France, Lufthansa and Delta can be viable for eligible small pets to selected EU airports. American does not accept carry-on pets transatlantic.
5
Before leaving New York
Design the return
Dogs returning to the US need the CDC Dog Import Form receipt; additional rules depend on where the dog has been during the prior six months.

Choose the journey

Transport options

Small dog/cat

Direct cabin to an EU airport

Choose an airline whose carrier rules your pet can genuinely meet; weigh the animal and carrier together where the airline uses an 8 kg limit.

Larger non-snub-nosed pets

Hold on an eligible airline

Check aircraft type, seasonal temperature embargoes, crate rules and every connection.

UK, unaccompanied, very large or complex moves

Cargo or specialist relocation

A professional shipper may be required. If travelling via the EU to Great Britain, you need to satisfy both borders and use an approved UK surface route.

Route-aware comparison

Airline pet policies

The operating carrier, direction, aircraft and available pet space all matter. “Cabin allowed” never means every flight.

Airline	Cabin	Larger pets	Route warning
KLM ↗	One cat or dog in Economy, or Business within Europe; pet plus carrier up to 8 kg and 46 × 28 × 24 cm.	Eligible pets can travel in the hold up to 75 kg combined, subject to aircraft, breed and connection restrictions.	Useful for eligible US→EU and departures from Great Britain. KLM does not accept pets into the UK as passenger cabin/hold baggage.
Air France ↗	Cats and dogs up to 8 kg including carrier may be eligible for the cabin, subject to route and availability.	More than 8 kg and up to 75 kg including carrier travels in the hold when accepted.	Useful for eligible US/Great Britain departures to France or onward EU travel. UK-bound pets are governed by the UK's cargo-only air-entry rule.
Lufthansa ↗	Small cats and dogs up to 8 kg including a soft carrier; maximum carrier size 55 × 40 × 23 cm.	Larger eligible animals may travel in the air-conditioned hold, with separate crate and breed rules.	A practical option for eligible trips to Germany and connections, but always check the operating carrier on codeshares.
Delta ↗	Small dogs and cats can travel in-cabin on eligible international routes when the carrier fits under the seat; booking is capacity-limited.	Standard checked-pet travel is not a general transatlantic option; international cargo uses a specialist shipper.	International in-cabin fee is currently listed as $200. No pets in cabin to or from the United Kingdom or Iceland.
American Airlines ↗	Carry-on pets are not accepted on transatlantic trips.	Ordinary checked pets are not offered; cargo is the practical route for most non-service animals, with checked-pet exceptions for qualifying military/State Department travel.	Not a normal in-cabin NYC→Europe option. Pets to the UK or Ireland require cargo rather than checked baggage.
British Airways ↗	Domestic pets are not carried in the cabin on any route; recognised assistance dogs follow a separate process.	Pets travel in the hold through PetAir UK when leaving the UK or IAG Cargo when entering the UK.	Treat this as a managed cargo product, not passenger checked baggage.

Plain-English answers

Frequently asked questions

Which NYC airport is easiest with a pet?

There is no universal winner. The decisive factors are the nonstop operating airline, aircraft, pet capacity, arrival-country inspection and ground journey—not JFK versus Newark alone.

Can I fly a dog from NYC to London in the cabin?

Not as an ordinary pet on a commercial flight into Great Britain. Direct entry is cargo. Some owners fly to an EU airport and continue by an approved surface route, but that requires both EU and GB-compliant paperwork.

Which airlines allow dogs in cabin from NYC to Europe?

KLM, Air France, Lufthansa and Delta publish eligible international in-cabin products on selected routes. Availability, aircraft and destination restrictions must be confirmed for the exact flight.
