The airline is accused of discrimination for making the test.
In order to board its flights in the UK and the rest of Europe, South African nationals are required to take a general knowledge test in their native language.
The low-cost carrier said the test would apply to anyone with a South African passport who flew to the UK.
They will be refused travel and given a full refund if they can't complete the survey.
Cases of fake passports were the reason for the tests, but they weren't required by the UK.
Criminals were easy to manufacture and sell fake South African passports according to the South African government.
The content of the test, including which side of the road South Africans drive on, would not determine if someone was a genuine passport holder, according to many South Africans.
According to reports, the 15-question test contains spelling andgrammatical errors.
A passenger from South Africa told the Financial Times that the test was exclusionary and that the airline did not consider the consequences of the test.
They said that it does amount to racial discrimination.
The airline was accused of racism by a user who said the airline restricted the movement of South African people based on the language they spoke. A bad look. It's pretty Racist.
Nomfundo Dlamini, a South African in the UK who said she was also given the test, told a South African radio station that the policy of the airline was "apartheid 2.0".
Many of the country's white settlers who came from the Netherlands were associated with the white minority rule that ended in 1994.
