Do you need a visa to transit airside?
In transit through the UK
You transit the UK airside if you arrive here on a flight, remain in the arrival lounge of the airport without passing through UK immigration control, and then depart on another flight from the same airport.
The UK government operates a DATV system for some countries. These countries are listed under 'More information' below.
You can transit the UK airside without a visa if:
you are a national of a country that is not in the list below; or
you are recognised as stateless under the 1954 UN Convention relating to the Status of Stateless Persons;
You hold a valid travel document issued by the UK government
You are a DATV national or recognised as stateless under the 1951 UN Refugee Convention and qualify for the DATV exemption under the 'transit without visa' concession - see under 'More information' below.
If you do not meet any of the above requirements, you must get a direct airside transit visa before you can transit the UK airside.
You cannot transit the UK airside if you are on your way to or from the Republic of Ireland, the Channel Islands or the Isle of Man.
How to apply for a direct airside transit visa
Depending on the country where you live, you may need to make your application online or using application form VAF6.
To find out which application method you should use, see 'More information' below.
You can download application form VAF6 and its guidance notes from the right side of this page.
As part of your application, you will need to enrol your fingerprints and facial image (known as 'biometric information') at a visa application centre.
Select your country in our country finder to find out:

You can copy this and take to the airline, at these airlines donot get this information. e.g in my country it is written for transit visa to France. if hold a valid US visa you donot need a transit visa, but Air France request transit visa and if you donot know or have this note you will miss your flight.
