If you have seen TWOV while checking airline, visa or transit information, it means Transit Without Visa. The term describes circumstances where an eligible traveller can pass through a country without obtaining the transit visa that might otherwise be required.
TWOV is not a universal permission to transit without a visa. The rules depend on the country you are connecting through and can also depend on your nationality, passport, residence status, visas you already hold, onward destination, airport, connection time and whether you remain airside.

This guide explains what the TWOV airline code means, how Transit Without Visa arrangements work and what families, autistic travellers and disabled travellers should check before relying on TWOV for a connecting journey.
What Does the TWOV Airline Code Mean?
TWOV stands for Transit Without Visa. IATA’s Timatic terminology includes TWOV within the visa section of its travel-document information, and governments also use the abbreviation when describing their transit immigration rules.
In simple terms, the TWOV code can allow an eligible passenger to travel through a country on the way to another destination without first obtaining a transit visa.
However, the word eligible is crucial. You cannot assume that a connecting flight qualifies for TWOV simply because you are only changing planes.
Is the TWOV Code an Airline Disability Code?
No. The TWOV airline code is not a disability or special-assistance code.
Passenger assistance uses other airline terminology and Special Service Request codes. Our guide to airline disability and SSR codes explains these in more detail.
The TWOV code instead relates to immigration and transit requirements. This distinction matters if you are checking a booking and trying to work out whether special assistance has been added correctly.
How Does Transit Without Visa Work?
Every country sets its own immigration and transit rules. A traveller who would normally require a visa may sometimes be allowed to connect through an airport without one if they meet the country’s TWOV conditions.
Depending on the country, the rules can consider:
- your nationality and passport
- your destination
- where you are travelling from
- whether you hold a visa or residence permit for another country
- the airport where you are connecting
- how long the connection lasts
- whether your onward flight is confirmed
- whether you stay in the international transit area
- whether you need to pass through border control
- whether you need to collect and recheck baggage
- whether you need to change airports or terminals
Because these requirements differ, TWOV should always be checked for your exact itinerary rather than treated as a general airline rule.
Airside vs Landside Transit
One of the most important things to understand when checking transit requirements is the difference between travelling airside and landside.
Airside transit generally means remaining within the secure international transit area of the airport without formally entering the country.
Landside transit means passing through border or immigration control. You may need to do this to collect baggage, change airports, use a hotel outside the secure area or make a connection where an airside transfer is not possible.
A country’s visa requirements can be different for these two situations. For example, current UK carrier guidance has separate rules for airside and landside Transit Without Visa arrangements.
Does Using the TWOV Code Mean You Can Leave the Airport?
Not necessarily. Some Transit Without Visa arrangements require passengers to remain within the international transit area. Others can permit eligible passengers to pass through immigration under specific conditions.
Never assume that the TWOV airline code means you can leave the airport for sightseeing, stay at an off-airport hotel or collect baggage landside. Check the rules for the country and your exact journey first.
China is a useful example of why terminology and eligibility need careful checking. China operates visa-free transit arrangements that can allow eligible travellers to enter permitted areas during qualifying itineraries. Our guide to China’s visa-free transit rules explains this separately, and I also have a guide to leaving the airport during a layover in China.
Example: TWOV in Canada
Canada has an official Transit Without Visa Program for certain eligible foreign nationals travelling through Canada to or from the United States.
The Canadian programme demonstrates how specific TWOV rules can be. Eligibility depends on factors including nationality, travel documents, participating airlines, approved Canadian airports, the onward journey and the length of the connection.
This is why seeing the words Transit Without Visa online is not enough to confirm that you personally qualify.
Example: TWOV in the UK
The UK also uses the term Transit Without Visa. Its current guidance distinguishes between airside and landside transit and sets conditions that travellers must meet.
For airside TWOV, current UK carrier guidance includes requirements relating to arriving and departing by air, holding a confirmed onward flight and having the correct documents for the onward destination. Additional requirements and exemptions can apply depending on nationality and the documents held.
UK immigration and transit requirements can change, so always use the current official UK government guidance for your own journey rather than relying on an old travel article or forum post.

Do Children Need to Meet TWOV Requirements?
Do not assume that a child is automatically covered by an adult’s transit status. Check the immigration and documentation requirements for every traveller on the booking, including babies and children.
For families, this is particularly important when family members hold different passports, nationalities, visas or residence permits.
The TWOV Transit Code and Checked Baggage
Baggage arrangements can affect whether a connection works without passing through immigration.
If your checked baggage is transferred automatically to your onward flight, you may be able to remain within the transit process where the airport and immigration rules allow it.
If you must collect your suitcase and check it in again, you may need to cross the border first.
Ask the airline whether your baggage will be checked through to your final destination. Do this before travelling rather than assuming that travelling on connecting flights guarantees through-checked baggage.
The TWOV Airline Code and Self-Transfer Flights
Be particularly careful with self-transfer itineraries. Separate tickets can require you to collect baggage, pass through immigration and check in again for the next flight.
That can turn what looks like an airside connection into a landside journey and may change the visa requirements completely.
Using TWOV and Long Layovers for Autistic Travellers
For autistic travellers and families, the immigration rules are only one part of planning a long connection. It also helps to understand exactly what the transfer will involve.
Before travelling, try to establish whether you will need to pass through immigration, collect baggage, change terminals, go through security again or remain in one transit area. Knowing the sequence in advance can make it easier to prepare visual supports and explain what will happen next.
If you need disability assistance during the connection, arrange this separately with the airline. The TWOV transit code relates to immigration requirements; it does not provide airport special assistance.
How to Check Whether You Can Transit Without a Visa
Before booking a connecting itinerary, check the transit requirements using your exact nationality, passport and route.
- Check the official immigration website for the country where you will transit.
- Confirm whether your nationality requires a transit visa.
- Check whether a TWOV exemption applies to you.
- Confirm whether you will remain airside or need to cross immigration.
- Check the permitted connection time.
- Confirm your onward ticket meets the rules.
- Check whether you need to collect baggage.
- Check whether a terminal or airport change is required.
- Make sure you hold all documents required for your final destination.
- Ask the airline to verify the transit requirements if anything is unclear.
Do this for every transit country on your itinerary. A visa exemption for your final destination does not always mean you can transit every country on the route without additional documentation.
TWOV Airline Code FAQ
What Does the TWOV Code Stand For?
The TWOV airline code stands for Transit Without Visa. It describes circumstances where an eligible traveller can transit a country without obtaining a transit visa.
Is TWOV the Same as a Visa?
No. TWOV means that an eligible traveller can transit without obtaining the visa that would otherwise be required. The traveller must still meet all applicable conditions.
Does the TWOV Transit Code Let Me Leave the Airport?
Not automatically. Some arrangements require travellers to remain airside, while other countries have specific provisions allowing eligible travellers to pass immigration. Check the rules for your transit country and itinerary.
Do I Need TWOV If I Do Not Normally Need a Visa?
TWOV is primarily relevant when considering whether a traveller who would otherwise need a visa can transit without one. Your normal visa-exemption or entry rules may already cover your journey, depending on the country.
Can an Airline Confirm TWOV Eligibility?
Airlines check travel documentation and may use systems such as IATA Timatic when assessing passenger requirements. However, you should also check the official immigration rules yourself before travel because eligibility depends on your individual documents and itinerary.
Is the TWOV Code a Special Assistance Code?
No. The TWOV code concerns transit immigration requirements. If you need disability or mobility assistance at the airport, this needs to be requested separately.
TWOV stands for Transit Without Visa and is used in airline reservations to indicate that a passenger is travelling through a country under its transit-without-visa arrangements.
Seeing the TWOV code on a booking does not itself give you permission to transit without a visa. Whether you qualify depends on the immigration rules of the country you are transiting through, including factors such as your nationality, passport, onward destination, length of transit and whether you need to pass through immigration.
Transit rules can also change, so always check the current requirements with the relevant government or immigration authority before travelling rather than relying solely on information shown in your airline booking.
If your itinerary changes, particularly if you are rebooked through a different country or airport, check the transit requirements again. A route that qualifies for TWOV in one country may require a transit visa in another.
