LIA is the second largest airport in Gauteng Province after ORTIA and the only airport in Gauteng, other than ORTIA, that has an international status, i.e. it has full customs and immigration facilities to allow cross border flights into and from South Africa.

The Airport is situated on the north-west of Randburg CBD, LIA has been the busiest general Aviation Airport in Africa in terms of aircraft movements.  Although it traditionally catered for the private, corporate and charter operators, it has recently become the secondary base of operations for a number of scheduled airlines offering services to destinations in South Africa as well as to neighbouring countries.
