Which Airlines Allow Small Dogs in the Cabin on Flights From Warsaw?
The essentials: LOT accepts dogs, cats and ferrets in the cabin up to 8 kg including carrier (55x40x20 cm Boeing, 45x30x20 Embraer); Lufthansa and KLM take small dogs via their hubs. Ryanair and Wizz Air accept no pets - certified assistance dogs only. You need a microchip, rabies shot and EU pet passport.
The short answer first
Flying out of Warsaw Chopin (WAW) with a small dog in the cabin is absolutely possible - but only on some airlines, and the divide is sharp. Poland's LOT and the big network carriers (Lufthansa, KLM and their partners) accept a small dog in the cabin under a weight limit. The low-cost giants do not: Ryanair and Wizz Air - which together carry a large share of Chopin's traffic - accept no pets in the cabin at all, only certified assistance dogs. If cabin travel with your dog is non-negotiable, your airline choice narrows before you even look at prices, and it usually means a full-service carrier, often with a hub connection.
Below is the airline-by-airline picture from official sources, then the paperwork, then the practical booking playbook. Rules change, fees change, and per-aircraft pet quotas are limited - always reconfirm on the airline's own page before booking.
LOT Polish Airlines: yes - dog, cat or ferret under 8 kg
Poland's national carrier is the straightforward yes from Warsaw. LOT's official pet-in-cabin page states you can take a dog, a cat or a ferret on board, subject to a per-aircraft limit on animal numbers. The core rules: the animal must travel the whole flight in a carrier (hard transporter or soft bag) it fits inside completely - able to stand, turn and lie down - and the animal plus carrier together may weigh no more than 8 kg. Accepted carrier dimensions are 55x40x20 cm on Boeing 787 and 737 aircraft, and 45x30x20 cm on the Embraer fleet (E70-E95) that flies many of LOT's European routes from Warsaw. One animal per passenger in the cabin (an exception allows two small animals of the same species in one carrier within the same 8 kg limit), and the service can be booked when buying the ticket or later, up to 12 hours before departure, via Manage My Booking - do it early, because the per-aircraft quota is the real constraint. Prices are shown during booking. Note for transatlantic readers: LOT also details special US entry rules for dogs introduced by the CDC in August 2024.

Ryanair and Wizz Air: no pets, assistance dogs only
This is where many Warsaw-based owners get caught, because the low-cost carriers dominate so many routes from Chopin (and all of Modlin's). Ryanair's help centre states it does not carry animals on board any flight, except guide/assistance dogs on certain routes. Wizz Air's official policy is the same shape: pets are not allowed on board, with the exception of guide dogs - certified assistance dogs are carried free on its EU flights (one per flight, documents sent at least 48 hours before departure), and emotional support animals are explicitly not accepted.
The practical consequence: for a weekend to London, Milan or Barcelona from Warsaw with a small dog in the cabin, the direct low-cost flight is not an option. You either fly a network carrier (usually with a connection), choose a destination LOT serves directly, or leave the dog at home. Booking the low-cost ticket first and asking later is the expensive version of this lesson.

Lufthansa and KLM: yes, with connections
The two big network alternatives from Warsaw both accept small dogs in the cabin. Lufthansa carries small dogs and cats weighing a maximum of 8 kg including their transport container as additional carry-on baggage in the cabin (larger animals go as excess baggage in the hold). From Warsaw this means flying via Frankfurt or Munich - which often prices surprisingly competitively against LOT's direct flights. KLM similarly accepts cabin pets with an advance reservation - its official guidance requires booking the pet at least 48 hours before departure and checking destination-country rules first - via Amsterdam. Both airlines apply their own carrier dimensions and fees, and both limit animal numbers per flight, so the reservation step is mandatory, not optional.
Worth knowing: because these carriers sell through tickets from Warsaw, the dog's reservation must cover every segment - a WAW-FRA-BCN itinerary needs the pet confirmed on both legs, and partner-operated segments can have different rules. Confirm the operating carrier on each segment before paying.

The paperwork: EU rules from the Polish veterinary inspectorate
Airline acceptance is only half the equation - the animal also needs its travel documents, and Poland's Chief Veterinary Inspectorate (Główny Inspektorat Weterynarii) publishes the official requirements for non-commercial travel with pets within the EU. The core trio for dogs: identification by microchip (tattoos are grandfathered only if applied before 3 July 2011 and clearly legible), a valid rabies vaccination recorded by a vet - with a 21-day wait after a first vaccination before travel - and an EU pet passport (paszport zwierzęcia), issued by authorised veterinarians in Poland. Non-commercial movement means up to five animals travelling with the owner, not for sale.
Leaving the EU changes the picture country by country: the UK, for example, does not accept pets in the aircraft cabin on arrival at all (they must arrive as cargo or via approved routes), regardless of what the airline would allow outbound - destination rules always layer on top of airline rules. For any non-EU destination, check both the destination's import rules and the airline's policy before booking anything. LOT's page illustrates the pattern with its detailed US dog-entry section, reflecting the CDC rules in force since August 2024.

The booking playbook from Warsaw
Step one: pick the airline before the fare. If the dog must be in the cabin, your realistic options from WAW are LOT (direct, widest route map), Lufthansa and KLM (one-stop via their hubs), plus a handful of other network carriers (Air France via Paris, Austrian via Vienna, SWISS via Zurich follow similar 8 kg cabin policies - verify each). Filtering flight search by carrier first saves re-doing the search later.
Step two: check the quota, then pay. Cabin pet spots are limited per aircraft - two to a handful depending on type - and popular routes sell out of pet slots while seats remain. Add the pet during initial booking (LOT allows it up to 12 hours before departure via Manage My Booking, but the quota may be gone by then; KLM requires at least 48 hours). The fee is charged per direction and typically runs to tens of euros - shown at booking.
Step three: weigh the full package honestly. The 8 kg limit is for dog plus carrier. A 7.5 kg dachshund in a 1.2 kg carrier does not fly in the cabin - weigh the loaded bag, not the dog. Soft bags help: they weigh less than hard crates and compress under the seat. If your dog is over the limit, the cabin option is gone and you are choosing between the hold (where offered), a pet-relocation service, driving, or a pet-sitter - decide early, because hold bookings have their own quotas and crate rules.
Step four: airport day. Arrive earlier than usual - LOT recommends three hours before departure for pet check-in, since document checks add time. The dog goes through security in your arms while the carrier goes through the scanner. At Chopin, the pet relief situation landside is limited, so walk the dog before entering the terminal. On board, the carrier stays closed under the seat in front of you for the whole flight - cabin crew will not make exceptions, and other passengers' allergies are the reason.
Step five: keep the documents in hand luggage. Pet passport, vaccination records, any destination-specific forms - paper or PDF offline, presented at check-in, not packed in the hold.
A note on assistance dogs - the exception that crosses the divide
Certified assistance dogs are the one category that flies in the cabin on every carrier discussed here, including Ryanair and Wizz Air. Wizz Air carries them free within the EU, limited to one dog per flight, with certification documents sent to its Special Assistance team at least 48 hours before departure; Ryanair accepts guide/assistance dogs on designated routes with its own pre-notification process. The keyword is certified: airlines check training documentation from recognised assistance-dog programmes, and Wizz Air's explicit exclusion of emotional support animals is the industry norm in Europe - an ESA letter that works domestically in the United States carries no weight at a Warsaw check-in desk. Owners of genuine assistance dogs should still notify the airline at booking, because the per-flight limit of one dog makes even this category quota-managed.
Frequently asked questions
Can I fly Ryanair or Wizz Air from Warsaw with a small dog in the cabin?
No. Ryanair carries no animals on board except guide/assistance dogs on certain routes, and Wizz Air likewise accepts no pets, only certified assistance dogs (free on EU flights, one per flight, documents 48 hours ahead). Emotional support animals are not accepted. For cabin pet travel from Warsaw you need a network carrier such as LOT, Lufthansa or KLM.
What is the weight limit for a dog in the cabin on LOT?
8 kg total - dog plus carrier. The carrier must close fully with the dog able to stand, turn and lie down, and fit 55x40x20 cm (Boeing) or 45x30x20 cm (Embraer). Book the pet service as early as possible; LOT accepts it up to 12 hours before departure, but per-aircraft quotas are limited.
What documents does my dog need to fly from Poland within the EU?
Per Poland's Chief Veterinary Inspectorate: an ISO microchip, a valid rabies vaccination (with a 21-day wait after a first-ever vaccination), and an EU pet passport issued by an authorised vet. Non-commercial travel covers up to five animals with the owner. Non-EU destinations add their own import rules on top.
